Isotropic and kinematic hardening of a high entropy alloy
Scripta Materialia, 2020 Abstract The contribution of kinematic hardening to the overall strain hardening of a high entropy alloy (HEA) was investigated for the first time ever. It was assessed for a single-phase equiatomic CoCrFeMnNi alloy based on a study of the Bauschinger effect. The observed occurrence of high back stresses signifies substantial kinematic hardening.

Multiplicative AF kinematic hardening in plasticity
International Journal of Solids and Structures, 2008 The basic innovation proposed in this work is to consider one of the two coefficients of the Armstrong and Frederick (AF) evolution equation for the back stress, function of another dimensionless second order internal variable evolving also according to an AF equation in what can be called a multiplicative AF kinematic hardening rule.

A non-linear kinematic hardening function [PDF]
, 1977 Based on the classical theory of plasticity and accepting the von Mises criterion as the initial yield criterion, a non-linear kinematic hardening function applicableboth to Melan-Prager's and to Ziegler's hardening rule is proposed. This non-linear hardening function is determined by means of the uniaxial stress-strain curve, and any such curve is ...

Investigation of advanced strain-path dependent material models for sheet metal forming simulations [PDF]
, 2006 Sheet metal forming processes often involve complex loading sequences. To improve the prediction of some undesirable phenomena, such as springback, physical behavior models should be considered.

Micromechanical analysis of kinematic hardening in natural clay [PDF]
International Journal of Plasticity, 2009 This paper presents a micromechanical analysis of the macroscopic behaviour of natural clay. A microstructural stress-strain model for clayey material has been developed which considers clay as a collection of clusters. The deformation of a representative volume of the material is generated by mobilizing and compressing all the clusters along their ...
