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 …

The micromechanics of ductile fracture has made enormous progress in recent years. This
approach, which was mostly developed in the context of structural integrity analysis, is …

With its combination of practicality, readability, and rigor that is characteristic of any truly
authoritative reference and text, Fracture Mechanics: Fundamentals and Applications quickly …

The extended finite element method allows one to model displacement discontinuities which
do not conform to interelement surfaces. This method is applied to modeling growth of …

Recent experimental evidence points to limitations in characterizing the critical strain in
ductile fracture solely on the basis of stress triaxiality. A second measure of stress state, such …

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 effects of stress triaxiality and initial porosity on void growth and coalescence are
studied in this paper. The representative material volume (RMV) is modeled by two …

The main purpose of this paper is to demonstrate that besides the stress triaxiality
parameter, the Lode angle, which can be related to the third invariant of the deviatoric stress …

The formation of cup-cone fracture in round bars and of slant fracture in plane strain
specimens is studied using the finite element (FE) method. Constitutive models proposed by …

The purpose of this work is to develop a constitutive model integrating anisotropic behaviour
and ductile damage for a X100 pipeline steel. The model is based on a set of experiments …
