S03 - Damage and fracture mechanics

The section focuses on damage mechanisms and fracture mechanics for all kinds of solid materials and structures. It aims at bringing together related research including experimental observations, modeling approaches and numerical techniques. In general, material failure is a complex process which may be considered on different length scales ranging from the atomistic up to the component, or even to the structural, level. Besides the material behavior of course also aspects of loading situations are crucial to describe failure. Thus, contributions focusing on static failure, dynamic failure or cyclic fatigue are equally welcome.

S04 - Structural mechanics

The section will focus on advanced theoretical, numerical and experimental models for the evaluation of the behavior of structures. The diffusion of innovative materials characterized by high strength, anisotropy and unconventional mechanical responses (metamaterials) pose new challenges to the design and the performance of various structural elements like beams, plates and shells. In particular, structural issues may appear at different scales when materials with an internal architecture are employed. Particularly welcome are models and algorithms for structures that address nonlinear material behaviors and investigate structural stability at different scales.

A wide range of open problems will be considered in the Section, from multi-scale modeling of heterogeneous materials, to the implementation of constitutive models in numerical applications until to the virtual testing of structural systems.

S07 - Coupled problems

Coupled problems arise in several applications. From a general point of view each problem containing more than one primary field is called a coupled one. Usually the class of coupled problems is subdivided into volumetrically coupled problems and problems with surface coupling. The class of volumetrically coupled problems contains e.g. the fluid flow in porous solids described by mixture theory, thermo-mechanically coupled problems, chemo-mechanically coupled problems and electro- or magneto-mechanically coupled problems while in the second class problems like the fluid-solid interaction via an interface are included.
All problems is in common that the presence of different fields in the numerical treatment requires special attention with respect to the multi-field formulation and the solution strategy. The session on coupled problems deals with all aspects mentioned above, i.e. ranging from modelling aspects to numerical solution strategies.

All these systems are central for technological advances in the chemical, pharmaceutical, environmental and food industries and crucial for the development of Microfluidics and Nanostructuring. Goal of this Section is to provide a representative overview of the latest developments in this area, covering models, numerical methods and experimental techniques but also surveying new physical insights and recent technical advancements.

S12 - Waves and acoustics

Waves are a ubiquitous natural phenomenon and acoustics are, besides surface water waves, the most obvious representatives, familiar to anybody and quantitatively known to any student of mathematics, physics or a technical subject. To this corresponds a long mathematical tradition, continuing today in the accurate numerical computation of linear and nonlinear wave phenomena.
Our session is devoted to the simulation and understanding of waves and wave interactions. The range of applications is thus very broad, while the focus is meant to be on the unifying physical phenomenon. In the past years we had numerous contributions from solid mechanics, porous media flow, turbulence and aeroacoustics, from crack detection to explosions.

S13 - Flow control

Many technical applications involving flows profit from trying to manipulate the boundary conditions or flow parameters in such a way as to generate a desired effect, like reduced drag, increased mixing, attenuated or increased turbulence or reduced sound emission, for example. The sophistication of the governing equations requires a broad range of research topics and methods to be covered, including analytical treatments, reduced-order modelling, passive manipulation of boundaries in experiments involving riblets, active manipulations using actuators, for example, or numerical approaches involving the adjoint equations, amongst others.
The speakers of our session reflect the broad application area of flow control and discuss difficulties in the application side and recent advances in the analysis, as well as experimental and numerical approaches.
