An alternative to kinematic hardening in classical plasticity
TL;DR: In this paper, an approach is proposed for the description of the plastic behavior of materials subjected to multiple or continuous strain path changes, which is not formulated with a kinematic hardening rule.
Journal ArticleDOI
Advanced Issues in springback
TL;DR: Wagoner et al. as mentioned in this paper presented a review of recent advances in the field of springback, the elastically driven change of shape of a metal sheet during unloading and following forming.

Mechanical response of AZ31B magnesium alloy: Experimental characterization and material modeling considering proportional loading at room temperature
TL;DR: In this paper, an evolving anisotropic/asymmetric continuum-based material model based on a Cazacu-Plunkett-Barlat (CPB)-type yield function is proposed to fit the material behavior as a continuous function of plastic strain.
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
An application of homogeneous anisotropic hardening to springback prediction in pre-strained U-draw/bending
TL;DR: In this paper, a constitutive model based on anisotropic hardening was used in the finite element (FE) simulations of springback and its performance was compared with that of conventional hardening laws.

The mathematical theory of plasticity
TL;DR: In this paper, the solution of two-dimensional non-steady motion problems in two dimensions is studied. But the solution is not a solution to the problem in three dimensions.

Constitutive equations for cyclic plasticity and cyclic viscoplasticity
TL;DR: In this paper, the cyclic constitutive equations developed and used at ONERA and LMT-Cachan are presented in detail in terms of a hierarchy of various models, including the Ohno-Kachi time-independent plasticity theory, two unified viscoplastic models by Walker and by Krempl and Yao, the new developments of the endochronic theory by Watanabe and Atluri.
Journal ArticleDOI
Time-independent constitutive theories for cyclic plasticity
TL;DR: In this paper, three different approaches are considered for the description of kinematic behavior: (i) the use of independent multi-yield surfaces, (ii) models with two surfaces only, (iii) the so-called "nonlinear-kinematic hardening rule" defined by a differential equation.
