Deformation and damage in Al/Al2O3
TL;DR: In this paper, the authors introduce damage criteria into a finite element microstructural model in order to foresee the degradation process in an Al 2 O 3 -particle reinforced Al(6061) composite during mechanical loading.

TL;DR: In this paper, a hierarchical model for deformation and fracture at the micro-, meso-and macro-level for metals and composites is presented. But the authors focus on unifying the method of approach to be supported by tests and calculations.

Simulation of elasto-plastic behaviour of an artificial 3D-structure under dynamic loading
TL;DR: In this paper, a special routine to generate a 3D heterogeneous structure is proposed to calculate a polycrystalline test-piece under plane shock wave as an example, and obtain numerical solutions using the finite-difference method.

The influence of transition phases on the damage behaviour of an Al/10vol.%SiC composite
TL;DR: In this paper, the authors investigated the damage behavior of the ductile matrix in particle reinforced metal matrix composites (MMCs) such as Al/SiCp, and determined critical failure parameters that affect the damage behaviour of the microstructure.

Computational mechanics of heterogeneous materials––influence of residual stresses ☆
TL;DR: In this article, a physically based micromechanical approach is applied in order to clarify the influence of residual stresses on local as well as global properties of MMCs, and a representative microstructural cut-out of an Al/10% SiC-composite is meshed with finite elements to take phase boundaries into account.
