Modeling of shear ductile fracture considering a changeable cut-off value for stress triaxiality
TL;DR: In this paper, a macroscopic ductile fracture criterion is proposed based on micro-mechanism analysis of nucleation, growth and shear coalescence of voids from experimental observation of fracture surfaces.

Strength modeling of sheet metals from shear to plane strain tension
TL;DR: In this article, a yield function is proposed to model sheet metal strength between shear and plane strain tension, which is expressed as an equation of the three stress invariants to take into account the pressure sensitivity, the Lode dependence and the strength-differential effect on material strength.

A modified yield function for modeling of the evolving yielding behavior and micro-mechanism in biaxial deformation of sheet metals
TL;DR: In this paper, a modified yield function with introducing a variable exponent to represent the evolving yield behavior was proposed and then employed to model the evolving yielding of the given metallic sheets, and simulated biaxial tension tests were conducted by using the established representative volume elements (RVEs) with a crystal plasticity model.

TL;DR: In this article, various experimental methods are investigated to characterize strain hardening behaviors up to large deformation under different stress states for an aluminium alloy sheet of AA5182-O. Strain hardening is obtained by both analytical computation and an inverse engineering approach under different loading conditions of shear, uniaxial tension, plane strain tension and equibiaxial tensile tension.

Frédéric Barlat,K. Lian +1 more
TL;DR: In this article, a yield function that describes the behavior of orthortropic sheets, metals exhibiting planar anisotropy and subjected to plane stress conditions is proposed, which is shown to give a reasonable approximation to plastic potentials calculated with the Taylor/Bishop and Hill theory of polycrystalline plasticity for plane stress states.

A six-component yield function for anisotropic materials
TL;DR: In this paper, a new six-component yield surface description for orthotropic materials is developed, which has the advantage of being relatively simple mathematically and yet is consistent with yield surfaces computed with polycrystal plasticity models.

Linear transfomation-based anisotropic yield functions
TL;DR: In this article, two convex formulations are proposed to describe the anisotropic behavior of metals and alloys for a full stress state (3D) in general terms, and the type of input data recommended for the description of plastic anisotropy in sheet samples is discussed.
