This paper summarizes our recent studies on modeling ductile fracture in structural materials
using the mechanism-based concepts. We describe two numerical approaches to model the …

In this paper void coalescence is regarded as the result of localization of plastic flow
between enlarged voids. We obtain the failure criterion for a representative material volume …

An ellipsoidal void model, which is based on a parallelogrammic void model, is proposed for
simulating ductile fracture behavior. It is used to analyze ductile fracture behavior in three …

Ductile fracture of structural metals occurs mainly by the nucleation, growth and coalescence
of voids. Here an overview of continuum models for this type of failure is given. The most …

A population of several spherical voids is included in a three-dimensional, small scale
yielding model. Two distinct void growth mechanisms, put forth by [Int. J. Solids Struct. 39 …

Two distinct mechanisms of crack initiation and advance by void growth have been identified
in the literature on the mechanics of ductile fracture. One is the interaction a single void with …

By adopting a suggestion made by Thomason, a new failure criterion for the Gurson‐
Tvergaard model has been recently introduced by the authors. In this study, a method based …

Based on two ductile fracture mechanisms, a new modification to the Gurson–Tvergaard–
Needleman (GTN) model is proposed for the simulation of ductile fracture behaviors under …

In this contribution we compare the yield function of Gurson (Gurson, AL, 1977. Continuum
theory of ductile rupture by void nucleation and growth—I. Yield criteria and flow rules for …

By comparing the micromechanisms of ductile fracture of metallic materials (void nucleation,
void growth and void coalescence) and the loading conditions in terms of local stresses and …
