Multiplicative AF kinematic hardening in plasticity [PDF]

open access: yesInternational 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]

open access: yes, 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 ...

Analysis of Undrained Seismic Behavior of Shallow Tunnels in Soft Clay Using Nonlinear Kinematic Hardening Model

open access: yesApplied Sciences, 2020
In this study, a soil–tunnel model for clay under earthquake loading is analyzed, using finite element methods and a kinematic hardening model with the Von Mises failure criterion.

Investigation of advanced strain-path dependent material models for sheet metal forming simulations [PDF]

open access: yes, 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.

Maximum Norm Wellposedness of Nonlinear Kinematic Hardening Models [PDF]

open access: yes, 1997

On Surface Grind Hardening Induced Residual Stresses [PDF]

open access: yes, 2014
Grind hardening process utilizes the heat generated in the grinding area for the surface heat treatment of the workpiece. The workpiece surface is heated above the austenitizing temperature by using large values of depth of cut and low workpiece feed ...

Micromechanical analysis of kinematic hardening in natural clay [PDF]

open access: yesInternational 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 ...

Plastic deformation modelling of tempered martensite steel block structure by a nonlocal crystal plasticity model

open access: yesTheoretical and Applied Mechanics Letters, 2014
The plastic deformations of tempered martensite steel representative volume elements with different martensite block structures have been investigated by using a nonlocal crystal plasticity model which considers isotropic and kinematic hardening produced

Single Cell Mechanics: Stress Stiffening and Kinematic Hardening [PDF]

open access: yesPhysical Review Letters, 2008
Cell mechanical properties are fundamental to the organism but remain poorly understood. We report a comprehensive phenomenological framework for the nonlinear rheology of single fibroblast cells: a superposition of elastic stiffening and viscoplastic kinematic hardening.
