Multibody dynamics enables the simulation of a wide variety of systems, all characterized by having multiple parts in relative motion with one another. Applications span from biological to engineering systems, requiring diverse capabilities which range from realtime simulation to high fidelity modeling of complex multidisciplinary systems. Goal of this minisymposium is to present a view on the latest developments in models and advanced numerical methods in multibody dynamics. Focus is on techniques that enable applications to complex reallife problems.

Failure of materials and structural components is an important issue as long as manmade constructions exist. The section focuses on damage mechanics and fracture mechanics for all kinds of solid materials and structures. It aims at bringing together related original research covering experimental observations, modeling approaches and numerical techniques. Moreover, material failure is a complex process, which may be considered on different length scales ranging from atomistic scale up to macro scale of engineering structures. Since failure behavior of materials strongly depends on loading situations, contributions addressing static, dynamic and multiaxial failure are welcome as well as fatigue problems.

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.

The section covers all fields of vibrational problems in solid mechanics or mechatronics including nonlinear effects. Submissions may address, for example, systems with nonlinear material behavior, nonlinearities in joints, mathematical solution methods (analytical or numerical), control or description of nonlinear behavior like bifurcations or chaos, or experimental idendification of nonlinearities.

The section focuses on constitutive modelling of natural and artificial materials subject to elastic and inelastic deformation processes. The aim is to compare new constitutive models formulated on both the phenomenological and the micromechanics basis to determine their validity by comparison of simulations with experiments. A wide range of open problems will be considered in the section, like multiscale modelling of heterogeneous materials, implementation of constitutive models in numerical applications, and the virtual testing of structural systems.

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, thermomechanically coupled problems, chemomechanically coupled problems and electro or magnetomechanically coupled problems while in the second class problems like the fluidsolid 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 multifield 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.

The topic of this session is the analysis and modeling of turbulent nonreactive and reactive flows based on DNS, LES, RANS, and experiments. A special focus is on fundamentals in turbulence, turbulent reactive flows, turbulent multiphase flows, modeling and simulation of complex turbulent flows, the interface of numerical algorithms, chemical and physical modeling, as well as highperformance computing with its application to turbulence.

The understanding and control of interfacial phenomena is one of the main challenges in multiphase fluid mechanics, at the crossroads of scientific disciplines like Mathematics, Physics, Chemistry and Engineering. Examples are particleladen flows, bubble columns, flows with cavitation, jet atomization, casting, oil recovery, film, boiling and foaming flows, as well as spreading and dewetting of (complex) liquids and biofluids. All these systems are central for technological advances in the chemical, pharmaceutical, energy, environmental and food industries. In addition, their behavior depends strongly on the typical time and length scales under consideration that are for example crucial for the development of micro and nano fluidics. In the latter case the validity of continuum fluid mechanics might be even questionable. The goal of this section is to provide an overview of the latest developments in this area, covering models at different scales, numerical, statistical and cognitive methods as well as experimental techniques but also surveying new physical insight and recent technical advancements.

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.

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, reducedorder 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.

This section will provide a forum for the presentation of historical and/or speculative studies on mechanics focusing on the relations between concepts from antiquity up to now, which could be of interest to historians of mechanics and physics as well as researchers in mechanics. The contributions of those authors who have benefited from the study of old theories for developing current models in the field of applied mechanics and mathematics will be also considered. This in order to highlight the importance of historical and epistemological perspective setting for the current and future developments in science. With these aims in mind, topics of applications will include (but are not limited to): Virtual work laws Variational methods and conservation principles Molecular foundation for continuum mechanics Coarse graining processes and the use of CauchyBorn rule Continuum and statistical thermodynamics Material deformation theories and experimental results in solid mechanics Inelastic deformations, damage and fracture Development and use of the Ricci's tensor calculus in deformation theories of solids, shells and fluids Mechanical models for ancient constructions
