Kinematic hardening in large elastoplastic strain

Engineering Fracture Mechanics, 1985
Abstract This work is devoted to large strain models for anisotropic hardening in elastic-plastic materials. The main part of the paper deals with various large strain extensions of the Prager model (linear kinematic hardening) within the framework of generalized standard materials.

Kinematic hardening in creep of Zircaloy

Journal of Nuclear Materials, 2016
Abstract Results of biaxial creep tests with stress changes on Zircaloy-2 tube samples are presented. A Hollomon-type viscoplastic strain hardening model is extended by the Armstrong-Frederic nonlinear kinematic hardening law, resulting in a mixed (i.e. isotropic and kinematic) strain hardening model.

Kinematic hardening of a porous limestone

Rock Mechanics and Rock Engineering, 1984
A concept for a kinematic hardening yield surface in stress space for Cordova Cream limestone (Austin Chalk) developed by Celle and Cheatham (1981) has been improved using Ziegler's modification of Prager's hardening rule (Ziegler, 1959). Data to date agree with the formulated concepts. It is shown how kinematic hardening can be used to approximate the

Kinematic hardening model for overconsolidated clays

Computers and Geotechnics, 2001
Abstract The proposed model puts a particular emphasis on accurate simulation of stress-strain behaviour of overconsolidated clays both within the small strain region of high stiffness and during the large-scale yielding. To achieve this, the model utilizes existing formulations which proved to be successful in description of clay behaviour in these ...

Nonisothermal Kinematic Hardening Law in Plasticity

Journal of the Engineering Mechanics Division, 1973
The incremental stress-strain relations have been formulated for nonisothermal kinematic hardening materials in which the yield surface is assumed to change its size with temperature. By following Prager’s assumption, the yield surface undergoes a translation in the direction of the plastic strain increment during the plastic flow.

Mathematical Analysis of Thermoplasticity with Linear Kinematic Hardening

Journal of Applied Analysis, 2006
The authors are experts in the field of elasto-plasticity, and published several articles on related topics, such as the Prandtl-Reuss flow law in plasticity. Here they consider thermoplastic materials with a linear evolution of kinematic hardening.

Kinematic Hardening and Plastic Instability under Plane Stress

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1975
AbstractThe main objective of this paper is to develop a criterion of tensile plastic instability which should be sufficiently general to include both the Bauschinger effect and anisotropy. The criterion so developed reduces to Moore and Wallace's condition for anisotropic materials, in case the Bauschinger effect is either completely neglected or it ...

On kinematic hardening and large plastic deformations

International Journal of Plasticity, 1986
The model of physically linear kinematic hardening is investigated in view of its convenient generalization to large strains. This generalization implies the definiton of differential operators in the form of objective tensor derivatives. It has been shown in the literature that an inconvenient choice of the time derivatives leads to a non- monotonic ...
