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
On linear transformations of stress tensors for the description of plastic anisotropy
TL;DR: In this article, the derivation of anisotropic yield functions based on the approach of linear transformations of a stress tensor is investigated for general and plane stress states, and the number of coefficients available for the description of plastic anisotropy is discussed.
Journal ArticleDOI
Finite element modeling using homogeneous anisotropic hardening and application to spring-back prediction
TL;DR: A finite element implementation of the recently proposed constitutive model (Homogeneous yield function-based anisotropic hardening model or HAH) that describes the plastic behavior of materials subjected to multiple strain path changes was developed.
Journal ArticleDOI
Strain rate potential for metals and its application to minimum plastic work path calculations
TL;DR: In this paper, a metric for the strain rate potential for plastically deforming metals is defined in six-dimensional deviatoric strain rate space, and its gradient provides deviateic stresses in the flowing material.
