A new model of metal plasticity and fracture with pressure and Lode dependence
Yuanli Bai,Tomasz Wierzbicki +1 more
TL;DR: In this paper, a 3D asymmetric fracture locus, in the space of equivalent fracture strain, stress triaxiality and the Lode angle parameter, is proposed.

Application of extended Mohr–Coulomb criterion to ductile fracture
TL;DR: In this article, the Mohr-Coulomb (M-C) fracture criterion is revisited with an objective of describing ductile fracture of isotropic crack-free solids.

Modification of the Gurson Model for shear failure
Ken Nahshon,John W. Hutchinson +1 more
TL;DR: In this paper, an extension of the Gurson model is proposed that incorporates damage growth under low triaxiality straining for shear-dominated states, which can be used to characterize important growth and coalescence features.
Journal ArticleDOI
Calibration and evaluation of seven fracture models
TL;DR: In this paper, a comparative study of seven fracture criteria that are included in libraries of material models of non-linear finite element codes is presented, and a detailed calibration procedure for each criterion is presented in the present paper.
Journal ArticleDOI
Failure of metals I : brittle and ductile fracture
TL;DR: In this paper, the first overview of failure of metals is presented, focusing on brittle and ductile failure under monotonic loadings, where the focus is on linking microstructure, physical mechanisms and overall fracture properties.

On the ductile enlargement of voids in triaxial stress fields
James R. Rice,D.M. Tracey +1 more
TL;DR: In this article, a variational principle is established to characterize the flow field in an elastically rigid and incompressible plastic material containing an internal void or voids, and an approximate Rayleigh-Ritz procedure is developed and applied to the enlargement of an isolated spherical void in a nonhardening material.

Mechanical behavior of materials
TL;DR: In this paper, the second-rank tensors of a tensor were modeled as tensors and they were used to model the deformation of polycrystalline materials and their properties.

On the mechanisms of ductile failure in high-strength steels subjected to multi-axial stress-states
J.W. Hancock,A.C. Mackenzie +1 more
TL;DR: In this article, the authors compared the size, shape and orientation of the holes which cause failure initiation with the isotropic continuum analysis of F.A. Mc Clintock (1968), with particular reference to the effects of directionality and stress state on the condition for flow localization to occur between holes.
