In this paper, we have investigated void growth in von Mises materials which contain
realistic porous microstructures. For that purpose, we have performed finite element …

A crystal plasticity model accounting for damage evolution and ductile failure in a single
crystal due to the presence of voids or micro-cracks is presented. An accurate, robust and …

In this work, we have brought to light the effect of material orientation on void growth. For that
purpose, we have performed finite element calculations using a cubic unit-cell model with a …

In polycrystalline materials, void growth is strongly dependent on its surrounding
microstructural environment such as grain morphologies, crystallographic orientations and …

In this paper, we investigate how the shear-modified Gurson-Tvergaard-Needleman (GTN)
model can be used to reveal the effect of manufacturing-process-induced porosity on the …

This study aims to model the effective mechanical response of highly porous materials using
computational homogenisation. A two-phase material is considered here in the form of a von …

Three different micromechanically-based computational models for fracture in porous ductile
solids are compared and assessed. Model A is a unit cell model of a porous ductile solid …

Damage evolution in polycrystalline aggregates is complicated by the intricate interplay of
crystallographic orientation of the porous grain and the surrounding anisotropic matrix …

The yielding, plastic flow and fracture of age hardenable aluminium alloys depend on the
quench rate to room temperature after the solution heat-treatment at elevated temperature …

In this study, the effects of including a dependency on the third deviatoric stress invariant in
the void evolution equation of the Gurson model are examined using unit cell calculations …
