Abstract
- Results from the modelling of the initiation and the evolution of microvoids governed by triaxiality and effective plastic strain in heterogeneous materials are presented. In particular, the damage evolution in a microalloyed thermomechanically treated steel consisting of brittle hard phases embedded in a ductile matrix is studied. Results obtained by numerical simulations using the finite element method are compared with experimental investigations of a notched cylindrical tensile bar. For this, two kinds of continuum damage models are used: the model of Rousselier, which assumes the yield stress as function of damage, and the concept of effective strains and stresses proposed by Lemaitre.
