TLDR
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.About:

Frédéric Barlat,Frédéric Barlat,J.C. Brem,Jeong W. Yoon,Jeong W. Yoon,Kwansoo Chung,Re Dick,D.J. Lege,Farhang Pourboghrat,Shi-Hoon Choi,E. Chu +10 more
TL;DR: In this article, a plane stress yield function that well describes the anisotropic behavior of sheet metals, in particular, aluminum alloy sheets, was proposed, which was introduced in the formulation using two linear transformations on the Cauchy stress tensor.

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.
Journal ArticleDOI
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.

Orthotropic yield criterion for hexagonal closed packed metals
TL;DR: In this article, a macroscopic orthotropic yield criterion, which can describe both the anisotropy of a material and the yielding asymmetry between tension and compression, is introduced.

A theory of the yielding and plastic flow of anisotropic metals
TL;DR: In this article, a theory is suggested which describes the yielding and plastic flow of an anisotropic metal on a macroscopic scale and associated relations are then found between the stress and strain-increment tensors.

TL;DR: In this paper, a general relationship between stress and plastic strain in polycrystalline aggregate is derived for any metal in which individual crystals deform by slipping over preferred planes under a critical shear stress.

Plastic behavior and stretchability of sheet metals. Part I: A yield function for orthotropic sheets under plane stress conditions
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.
