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 …

A mechanism of ductile fracture involving the interaction of relatively large voids with small-
scale voids is studied by a computational model. The larger voids are described as circular …

This paper investigates the possibility that ductile fracture occurs by the McClintock-Berg
mechanism of localization of deformation within a narrow shear band, owing to the …

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 …

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 …

Ductile fracture of HY-100 steel at high stress triaxialities occurs by a void-sheet mode of
failure in which large elongated voids, formed at MnS inclusions, coalesce as a result of a …

This paper presents a unit cell model based on the observation that ductile fracture occurs
when plastic flow is localized in a band. The unit cell consists of three void containing …

Many metals that fail by void growth and coalescence display a macroscopically planar
fracture process zone of one or two void spacings in thickness; outside this region, the voids …

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 …

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 …
