Co-Organizer: Daniel Hochlenert

Technische Universität Berlin, Berlin, Germany

The aim of the Mini-Symposium is to collect and enhance the research of nonlinear dynamics in the context of technical systems and applications. Many investigations of nonlinear dynamics concentrate on scientific examples to explain underlying effects but do not discuss the effects in combination with technical applications. The intention of the Mini-Symposium is to focus on the step from theoretical investigations of nonlinear differential equations on the one hand towards technical systems showing a nonlinear dynamic behavior on the other hand. Therefore presentations of the Mini-Symposium for example might cover experimental techniques identifying nonlinear effect, efficient mathematical mechanical modeling of technical systems, stochastic excitation of nonlinear systems, and the active or passive control of corresponding systems, whereas special regard is given to technical applications.

The ever increasing speed of computers has led the field of computer simulation to new challenging frontiers. Computational models have been used to predict the behavior of complex engineered systems such as spacecrafts, flexible risers, oil platforms, microelectronic components, among others. Being on the core of Model Validation, the fields of Inverse Problems and Uncertainty Quantification have shown to be invaluable within any Engineering Program whose decisions are to be made based on computational models. The purpose of the present section is to bring together researchers working on Inverse Problems and Uncertainty Quantification applied to Sound and Vibration modeling and applications.

The modern vertical transportation installations involve great technological and engineering challenges. The current trends involve construction of tall office and residential towers where the development and control of safe high-speed elevators and energy efficient escalator systems has become an important issue. In underground mining the safety of personnel and profitability rely on stable designs of hoisting installations. In space transportation technologies vertical propulsion systems based on various applications of momentum exchange and electrodynamic interactions with planetary magnetic fields are being proposed. The adverse dynamic responses and interactions pose serious operational and serviceability problems in these systems. In this context the Mini-Symposium is aimed at improving the understanding of the dynamic phenomena and vibrations in vertical transportation systems. Technical papers covering analytical, numerical, and experimental research in these areas are invited for submission.

Beam-like structures occur in practically all areas of engineering practice, from the construction and automotive industry to offshore and aerospace structures. Beam structural models have always attracted the engineering and scientific community due to their simplicity (unidimensionality) and computational efficiency. Recent years have witnessed a growing interest in “advanced” beam models for non-linear analyses, using e.g. “geometrically exact” theories and even including cross-section in-plane and out-of-plane deformation, which is essential to capture the non-linear behavior of thin-walled beams. This session aims at bringing together researchers devoting their investigation to the dynamic and vibration behavior of beams using advanced beam models, in order to discuss the most recent developments and to provide an international forum for the discussion of the current state-of-the-art.

Thin plates and shells made of isotropic, orthotropic and sandwich materials are often subjected to different kinds of mechanical and thermal loading and as a result such structural components are prone to deformations, bucking and vibrations for which proper analysis are required to be made by using linear and nonlinear theory.

Based on linear and nonlinear theories a great deal of research works on dynamic analysis of thin plates and shell structures under mechanical, thermal and other types of loadings with different kinds of boundary conditions have been carried out by many researchers. Still there is a scope for further research.

Intensive research in this area have wide scope in engineering and building designs, especially in several of the present day high-technology industries, high speed spacecrafts, nuclear power plants, offshore and ship building mechanics, storage and high-rise structures including applications in many branches of engineering mechanics and aeronautics.

The major problem of cognitive neuroscience is to understand how our behavioural processes are related to the workings of brain and nervous systems. To understand the subjective mental processes in a meaningful and quantitative way a new level of description is needed. Of late a trend has emerged to study different forms of cognition in terms of their neural-oscillation correlates. Questions have been raised whether the combined and synchronous actions of nerve cells, glial cells and their associated molecules can explain the underlying mechanism of cognition.

Although over the last decade some insight has been gained, especially with advances in brain imaging, a unified interpretation, however, is very much lacking. It is to be emphasized that experimental and numerical works are mandatory for any scientific progress but it can reveal its full value only when it is embedded within a conceptually sound theoretical frame work. The aim of the session is to explore this possibility.

MS12: Trefftz-Type Methods for Vibration Problems

Trefftz-type methods are a class of numerical methods for solving boundary-value problems. As opposed to the Rayleigh-Ritz strategy, Trefftz methods seek the combination of free-field solutions of the governing equation that best fits its initial/boundary conditions. Thus, Trefftz approach yields approximation bases that contain physically meaningful information on the modelled phenomenon, making them particularly well suited for vibration propagation problems. Moreover, Trefftz formulations typically lead to boundary integral descriptions of the discretized problems. This trait lifts the restrictions placed on the topological complexity of the domain/elements. The symposium is meant as a forum for the dissemination of theoretical advances and practical applications of any of the Trefftz-type methods, in the field of vibration modelling. Multidisciplinary communications are especially encouraged and the presence of authors from different scientific fields will actively be sought.

MS13: Time-Periodic Systems: Modelling, Behaviour and Applications

Corresponding Organizer: Fadi Dohnal

TU Darmstadt, Darmstadt, Germany, Email:

Co-Organizer: Ivana Kovacic

University of Novi Sad, Novi Sad, Serbia

Co-Organizer: Matthew Phillip Cartmell

University of Sheffield, Sheffield, UK

This Mini-Symposium is concerned with modelling, investigations of phenomenological behaviour and applications of time-periodic (TP) systems. Time-periodicity can appear directly as a variation of system parameters, implicitly through boundary conditions, e.g. in axially loaded structures, rotor shafts in anisotropic bearings, for which the prediction of a safe operating regime is important, or as autoparametric interactions; emerging fields in physics and engineering on the micro- and nano-scale introduce it to improve vibration performance.

Potential topics include: 
-New theoretical or experimental models; 
-Developments in time-solution techniques and bifurcation theory; 
-Studies of phenomena arising in TP systems (e.g. autoparametric interactions, strong nonlinearity, multi-frequency excitation or quasi-periodicity); 
-Applications of parametric resonance (e.g. micro-ring gyroscopes, structural filters); 
-Applications in higher dimensional problems and complex structures.

Recent development of transportation leads to new problems regarding analysis of dynamic behaviour of rail and road systems. Therefore new modelling approaches, accompanied by numerical simulations, are needed for better representation and prediction of real structures dynamic phenomena. This session aims at bringing together researchers dedicating their investigations to solutions related to dynamic behaviour of transportation systems. The theoretical results (especially analytical and semi-analytical solutions) always reflect important features of the investigated models allowing their effective parametrical analysis and leading to better prediction of possible scenario when one deals with real structures. Experiments and measurements lead to models validation and better characteristics of structures behaviour. Interdisciplinary ideas regarding physical problems appearing in constructions subjected to dynamic excitations (mainly due to moving loads) are welcome in this symposium.

MS18: Nonlinear Structural Dynamic Analysis - From Theory to Practice

Corresponding Organizer: Aram Soroushian

International Institute of Earthquake Engineering and Seismology (IIEES), Tehran, Iran, Email:

All physical phenomena are dynamic and nonlinear. Concentrating on structural systems, continuous, broad, and thorough study, on nonlinear dynamic analysis, is necessary, especially, due to the analyses complicatedness, computationally expensiveness, probable inaccuracies, and the fact that, the evaluation of inaccuracies is not simple, and may lead to improper structural designs and different losses. As a step forward, papers on all issues related to nonlinear structural dynamic analysis are very welcome to the mini-symposium MS 18. The focus will be on modeling the different nonlinear structural dynamic behaviors, innovative analysis methods, continuation methods, inaccuracies of the analyses, numerical stability in presence of nonlinearity, errors evaluation, verification/validation issues, benchmark problems, computational efficiency, the role of the analyses in structural codes and standards, and, finally, historical notes and memorandum of the past experts and scientific giants.

MS19: Dynamics, Identification and Control of Mechanical Systems

Corresponding Organizer: Carmine Maria Pappalardo

University of Salerno, Salerno, Italy, Email:

The goal of the Mini-symposium is to present scientific works related to Dynamics, Identification and Control of mechanical systems in order to obtain a mutual integration of these three disciplines. Indeed, the aim is to see Dynamics, Identification and Control of mechanical systems according to an unified framework in order exploit them in practical applications. The description of the motion of mechanical systems is the core of Multibody Dynamics. System Identification is the art of determining a mathematical model of a physical system by combining information obtained from experimental data with that derived from an a priori knowledge. In particular, applied System Identification methods allows to get modal parameters of a dynamical system using force and vibration measurements. The purpose of Control Theory is to study how to design a control system which can influence the dynamics of a mechanical system. Consequently, these three subjects are actually strongly linked together.

MS20: High Intensity Ultrasound Systems

Gottfried Wilhelm Leibniz University, Hannover, Germany, Email:

High Intensity Ultrasound Systems are used in process technology to improve mechanical and chemical reactions. Wave phenomena and their interaction with the fluid as well as cavitation, particle transport and surface chemistry play a major role in these systems.

Processes in the ultrasound chamber rely on focusing of ultrasound. Therefore the design of the transducer, the interface between transducer and fluid, and the design of the reaction chamber itself need to be optimised with respect to the target application.

This mini-symposium concentrates on the following three fields:

A) Design and Control of Transducer Systems
B) Modeling of wave propagation in process fluid
C) Modeling of fluid – particle interaction

We expect contributions from the areas of Mathematical Modelling, Experimental Techniques, Structural Dynamics, Wave Problems, Fluid-Structure Interactions, and Vibration Control.

MS21: Innovative Concepts to Influence or Monitor Vibration Systems

Hamburg University of Technology, Hamburg, Germany, Email:

Co-Organizer: Marc-André Pick

Hamburg University of Technology, Hamburg, Germany

In dynamics sophisticated and powerful tools have been developed for modeling the behavior of technical systems. Multibody systems, methods using variational principles such as Finite Element Methods or Boundary Element Methods, and even combinations of these three methods are available. Structural nonlinearities can be included into each of them. Based on these models the dynamic behavior can be investigated for different types of excitations and structural properties can be optimized. Model-free methods can lead to monitoring tools even if necessary quantities cannot be measured directly. This mini-symposium is intended to bring together scientists working mainly on innovative concepts to influence or monitor vibration systems. Both, theoretical concepts and experimental solutions to reduce or stimulate vibrations using passive and/or active devices as well as model based vibration monitoring tools are welcome to be presented in this mini-symposium.

Eigenvalue assignment is a technique used for reassigning the eigenvalues of a mechanical system using active feedback control, in order to achieve a more desirable performance. In practice, eigenvalue assignment can be implemented for linear systems using the receptance method, which utilises measured receptances instead of the usual mass, damping, and stiffness matrices to categorise the open-loop system. The aim of the proposed Mini-Symposium is to expand the receptance method to a variety of non-linear systems, using the classic Duffing oscillator as an example. Since most non-linear systems exhibit complex, amplitude-dependent dynamics, eigenvalue assignment for non-linear systems is much more complex than for their linear counterparts.

Proposed topics include:
- Modelling nonlinearities using a harmonic balance, Volterra, or NARMAX approach
- Modelling changes to the open-loop pseudo-receptance as a result of feedback control
- Applications to saturated non-linear systems.

The optimization is essential for the control of the structures subjected to excitations with high impacts like earthquakes and winds. In passive controlled structures, the optimization of the device properties and the location is important for the best performance and economy. On the other hand, the active control systems must be optimized to overcome stability, feasibility and energy problems. The aim of the mini-symposium is to bring together all leading academicians working on structural control using numerical optimization, metaheuristic algorithms, optimal control theory and other new and well-known methods. The original numerical and experimental studies employing new methods and the original applications of existing methods are accepted.

The aim of this mini-symposium is the collection of works in the area of development of materials and systems for the dissipation of the energy of vibrations induced by external loading in a structure, or component. Energy absorption by mechanical or materials damping is one of the most important problems for vibrations control and suppression in mechanical and structural engineering.

The reduction of vibrations in systems for civilian applications can improve the stability of structures and guarantees longer service life, therefore a lot of efforts have been dedicated to develop materials or to improve traditional materials and systems for controlling the stability of such structures.

This mini symposium invites all papers that have as main objective the development of materials or structures/components for the reduction of vibrations in structural engineering. It includes the modeling of such a behavior both by analytical and numerical approaches.

The development of efficient techniques to drill deep boreholes to access the Earth’s underground energy resources is a great challenge of our time, affording engineering sagacity and innovation capacity. Technological developments are somehow ahead of scientific methodology, demanding a huge amount of theoretical modeling and experimental validation. Developments of robust methods to control and mitigate the self-excited vibrations of drilling systems, formulation of comprehensive models for predicting borehole trajectories that can be used to optimize the control of rotary steerable systems, and understanding of efficient means to fragment rocks in the pressure environment of deep holes are examples of such scientific challenges. With sessions topics like drillstring vibrations, drill bit dynamic behavior, bit-rock interaction modeling, impacting techniques, borehole propagation models, torque & drag and downhole measuring techniques, we hope that lively discussions will emerge.

Corresponding Organizer: Tatjana Pyragiene

Semiconductor Physics Institute, Vilnius, Lithuania, Email:

Synchronization is caused by the interaction between two or more systems and manifests itself in physical, biological and chemical systems. Nowadays this phenomenon of nonlinear dynamics is widely employed in engineering, medicine as well as in communication, so the design and modeling of the coupling of oscillators is vital.

Different kinds of synchronization were developed, e. g., identical, general, phase, anticipating synchronization, investigating connected autonomous and forced, non-chaotic and chaotic oscillators. It is achieved by applying the mutual and unidirectional coupling, constructing the complicated coupling matrix, including a delay-shift term in the coupling et cetera.

The aim of this mini-symposium is to invite researchers in different fields of nonlinear dynamics to present their recent works in investigating of synchronization phenomenon and discuss the challenges and opportunities we are facing in constructing coupling schemes.

State Key Laboratory of Traction Power, Southwest Jiaotong University, China, Email:

Railway vehicle vibration’s a special structure vibration problem. There’re a multitude of sources of vibration, such as wheel/rail contact, catenary/pantograph contact, vehicle internal excitation. Hunting movement, a typical self-excited vibration, is the key to running safety. High-speed railway vehicles have developed their own basic structure components, such as the aluminium alloy car body, welded bogie frame, wheelset with hollow axles, primary and secondary suspension systems and so on. Matching parameters problems are still the research focus. Active suspension, passive suspension, semi-active suspension and lightweight design are applied popularly in vehicle design to avoid unnecessary vibration. With the increasing of speeds, the interactions between the train and tracks, catenary and air flow are intensified obviously. How to match the structural and suspension parameters? What’s the most effective way to isolate vibration? Vehicle designers are all working on the answers.
