Plane stress yield function for aluminum alloy sheets—part 1: theory
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.
Journal ArticleDOI
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.
Journal ArticleDOI
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.
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.
Journal ArticleDOI
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.
