Kinematic hardening model considering directional hardening response
International Journal of Plasticity, 2018Abstract This paper proposes a kinematic hardening model to capture both asymmetric plastic behavior (early-reyielding, transient Bauschinger effect and permanent softening) and directional hardening (anisotropic hardening) response at the same time.

A model comprising work hardening and solid solution hardening
Physica Status Solidi (a), 1978In a former paper the problem of solid solution hardening and work hardening of solid solutions was treated for the case of two types of obstacles with relative concentrations xs and xw, and strengths ƒs and ƒw. The resolved shear stress can be formally written as τ2/(Gb/l0)2 = τ(ƒs, ƒw, xs, xw) where G and b have their usual meaning and l0 denotes ...

This paper presents simulation of the work hardening curves of metals deformed at a constant temperature and strain rate under conditions of dynamic recrystallization (DRX). A work hardening model has been developed based on the evolution of the dislocation structure during deformation.

Heterogeneous Hardening Plasticity Model for Concrete
Journal of Structural Engineering, 1994A heterogeneous hardening rule is proposed for concrete in this paper. Being different to the hardening rules in common use, by which the development of the subsequent yield surfaces from the initial yield surface is at an uniform rate with respect to the variation of the hardening parameter, the heterogeneous hardening rule deems that the development ...

AbstractAn anisotropic hardening description is proposed on the basis of the Generalized Isotropic Hardening (GIH) rule. The key concept of the GIH rule is that any proper stress state inside or on an yield surface can be the homologic center of isotropic hardening.

Numerical modelling of hardening polymers
Mechanics of Composite Materials, 1996An approach to complex modelling of structural, temperature and stress — strain states of hardening polymers is suggested. The approach does not basically need new experimental data. Numerical methods are used. The approach is employed with some programs. Some of the results of test calculations are given in the article.

The present paper proposes two rules to develop a new kinematic hardening model. The first rule regulates the movement of the yield surface. It states that during loading, the yield center moves such that the kinematic hardening of the yield surface results in a plastic strain rate that an isotropic hardening model would also predict.
