The macroscopic fracture in plane strain is known to be shear-like in ductile materials. In
most structural materials, fracture starts after diffuse necking, at the centre of the specimen …

For polycrystalline metals ductile fracture most often occurs by nucleation, growth and
coalescence of microvoids. Void nucleation and growth decreases the load carrying …

Propagation of cracks in ductile materials is well known to occur through two possible
mechanisms: coalescence of cavities and formation of shear bands ('void sheet …

Plastic anisotropy in the form of texture development and void shape evolution can
significantly affect damage growth rates and overall strain to failure in ductile materials. A …

Significant progress has been recently made in modelling the onset of void coalescence by
internal necking in ductile materials. The aim of this paper is to develop a micro-mechanical …

Abstract The Gurson–Tvergaard–Needleman (GTN) model has provided a powerful
description of the nucleation growth and coalescence of micro voids, but it has limitations in …

Two modes of plastic flow localization commonly occur in the ductile fracture of structural
metals undergoing damage and failure by the mechanism involving void nucleation, growth …

The failure of ductile materials subject to high loading rates is notably affected by material
inertia. We analyze how strain localization and fracture are influenced by inertia through …

Gurson type constitutive models that account for void growth to coalescence are not able to
describe ductile fracture in simple shear, where there is no hydrostatic tension in the …

Ductile fracture is a process involving microvoids nucleation and growth, ending abruptly by
void coalescence. The nature of the local mechanical fields is of prime importance to model …
