A parallel elastic and inelastic heterogeneous multiscale method for rate-independent materials

Shirazi Nejad, Ramin

Abstract:
In this thesis, we consider a heterogeneous multiscale method for elasticity and its extension to inelasticity within a two-scale energetic approach for rate-independent material models. For the efficiency, we propose a parallel realization of an FE² method which allows the computation of 3D microstructures with fine resolutions. The efficiency of this method is demonstrated for a simple damage model combined with elasto-plasticity describing a PBT matrix material with firmly embedded glass fiber inclusions.
