Rigorous derivation of an effective model for coupled Stokes advection, reaction and diffusion with freely evolving microstructure
Markus Gahn, Malte A. Peter, Iuliu Sorin Pop +1
We consider the homogenisation of a coupled Stokes flow and advection-reaction-diffusion problem in a perforated domain with an evolving microstructure of size . React…
A Darcy law with memory by homogenisation for evolving microstructure
David Wiedemann, Malte A. Peter
We consider the homogenisation of the instationary Stokes equations in a porous medium with an a-priori given evolving microstructure. In order to pass to the homogenisation limit,…
Effective T-matrix of a cylinder filled with a random 2 dimensional particulate
K. K. Napal, P. S. Piva, A. L. Gower
When a wave, such as sound or light, scatters within a densely packed particulate, it can be rescattered many times between the particles, which is called multiple scattering. Mult…
Computational polyconvexification of isotropic functions
Timo Neumeier, Malte A. Peter, Daniel Peterseim +1
Based on the characterization of the polyconvex envelope of isotropic functions by their signed singular value representations, we propose a simple algorithm for the numerical appr…
Characterization of polyconvex isotropic functions
David Wiedemann, Malte A. Peter
Polyconvexity is an important concept in the analysis of energies related to elasticity. A function is called polyconvex if it can be written as a…
Multidimensional rank-one convexification of incremental damage models at finite strains
Daniel Balzani, Maximilian Köhler, Timo Neumeier +2
This paper presents computationally feasible rank-one relaxation algorithms for the efficient simulation of a time-incremental damage model with nonconvex incremental stress potent…
