A Turbulent Dispersion Model for Particles or Bubblesticle and bubble transport by turbulence. The model is the “standard” two-fluid model for two-phase flow that is derived using ensemble averaging, and consequently that model describes macroscale motions for two-phase flows. The microscale origin of the turbulent dispersion force will be highlighted

Discontinuous Galerkin Method for Modeling Flow and Reactive Transport in Porous Mediaport of radionuclides, chemicals, and/or biological species through soil and aquifers. The simulation of such processes with chemical interactions is inherently ill-conditioned due to widely varying scales. Species can be present at trace amounts, equilibrium constants and other parameters can vary

Modelling and numerical simulation of martensitic transformationnuum mechanical level by partial differential equations. Here the stored energy density is used, which is a rotationally invariant and nonconvex function of the transformation gradient with minima at several wells. The energy dissipation observed in physical experiments is modelled by an additional

Coupling of Homogenization Techniques with Multigrid Solvers for Unstructured Meshesf strongly heterogeneous, linear elastic materials. The micro-structure is assumed to be resolved sufficiently well. The key contribution is the formulation of new physically motivated approaches for linear-elastic composites with arbitrary micro-structures. This task is achieved by means of a numer

Upper and lower semicontinuity of a stable set for rate-independent processesmechanics, engineering and arises whenever the systems under consideration excited quasistatically. This approach is based on an energy functional ., ·) and a dissipation functional .. We study the upper and lower semicontinuity of a stable set for (.., .), . ≥ 0, and the uniqueness question.

Multiscale Modeling in the Mechanics of Materials: Cohesion, Interfacial Interactions, Inclusions anconstraints of general character. These models take into account the superficial effects and internal interactions similar to interatomic forces of coupling. The models of media with a continuous field of defects of various types are considered. Descriptions of the media with defects, cohesion field

Computational Homogenization of Materials with Microstructures Based on Incremental Variational Formzation principle for the local constitutive material response we define a minimization problem for the incremental boundaryvalue problem of standard dissipative solids. The existence of this principle allows the determination of micro-structure developments in non-stable dissipative materials based

Aspects of Material Modelling of Pyrolytic Carbonlarly interesting for industrial application due to their high strength and light weight. One of the difficulties in hierarchical modelling of this composite [1] is that the material constants of pyrolytic carbon are unknown. The pyro-C shows four forms with a different polycrystalline structure: is
