Ductile rupture in metals is a phenomenon that affects a wide range of applications from
forming of automotive body panels to failure of pressure vessels. The incipient stage …

Publisher Summary An important failure mechanism in ductile metals and their alloys is by
growth and coalescence of microscopic voids. In structural materials, the voids nucleate at …

This is the first of three overviews on failure of metals. Here, brittle and ductile failure under
monotonic loadings are addressed within the context of the local approach to fracture. In this …

The past 20 years have seen substantial work on the modeling of ductile damage and
fracture. Several factors explain this interest.(i) There is a growing demand to provide tools …

A model for the axisymmetric growth and coalescence of small internal voids in elastoplastic
solids is proposed and assessed using void cell computations. Two contributions existing in …

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 …

Deformation and fracture are investigated at room temperature in steel through tension and
compression tests. Round smooth bars and cylinders are used to characterize the …

Recently, a complete Gurson model has been introduced by the authors. The complete
Gurson model is a combination of the modified Gurson model which deals with microvoid …

The aim of this paper is to incorporate plastic anisotropy into constitutive equations of porous
ductile metals. It is shown that plastic anisotropy of the matrix surrounding the voids in a …

This work makes use of a recently developed “second-order” homogenization model to
investigate failure in porous elasto-plastic solids under general triaxial loading conditions …
