Stress integration of the Drucker-Prager material model with kinematic hardening [PDF]

Theoretical and Applied Mechanics, 2015
This paper presents a method for implicit stress integration of the Drucker-Prager material model with kinematic hardening. The stress integration of the material model is conducted using the incremental plasticity method, while the kinematic ...

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 ...

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

Theoretical 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]

Physical 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.

Springback prediction of magnesium alloy sheet with nonlinear combined hardening

工程科学学报, 2017
Springback is regarded as one of the main defects that occur in sheet-metal forming processes. Therefore, improving its prediction accuracy, especially under highly nonlinear conditions, is important for researchers. In this paper, constitutive equations

Evaluating the effectiveness of combined hardening models to determine the behavior of a plate with a hole under combined loadings

European Mechanical Science, 2022
Geometrical discontinuities in a material such as holes and notches on machine elements are called as critical regions due to the stress concentrations. They are the potential failure initiation locations Therefore, researchers put significant effort on ...

Characterisation and modelling of anisotropic hardening behaviour of cubic and hexagonal close packed polycrystalline metals

Philosophical Magazine Letters
In this study, anisotropic non-proportional hardening behaviour of the sheet metals with different crystalline structures is investigated. The investigated materials particularly exhibit the Bauschinger effect and complex transient hardening behaviour ...
