One dimensional evolution rule is used as basis for generalization to three-dimensional finite deformation applications. It is shown that the strain-rate is not a flux and hence it should not be employed in the flow rule in Kinematic hardening theory.

On the identification of kinematic hardening with reverse shear test
Engineering with Computers, 2014An inverse analysis methodology for determining the parameters of the kinematic law of sheet metals is proposed. The sensitivity of the load versus displacement curves, obtained by reverse shear tests of rectangular and notched specimens, to the kinematic law parameters are studied following a forward analysis, based on finite element simulations ...

Mathematical Analysis of Thermoplasticity with Linear Kinematic Hardening
Journal of Applied Analysis, 2006The 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.

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.

On generalized kinematic hardening theory of plasticity
Ingenieur-Archiv, 1975An isotropic theory of plasticity is proposed in which expansion, rotation and translational movement of the yield surface are taken into account. The properties of the anisotropic parameters are investigated for some measured data. The incremental constitutive equation is then derived.

On modelling of kinematic hardening for ratcheting behaviour
Nuclear Engineering and Design, 1995Abstract A kinematic hardening rule is formulated on the assumption that each component α i of back stress has a critical state for its dynamic recovery to be fully activated. The rule has a feature that only the projection of plastic strain rate to the direction of α i contributes to the dynamic recovery.

Nonlinear kinematic hardening in coupled thermoplasticity
Materials Science and Engineering: A, 2009Paper deals with permanent deformation of metals within nonisothermal environment. As it is generally known, metals are easier shaped if the specimen in heated. Furthermore, dimensions of an object also change with temperature variation. In that way, thermal effects influence mechanical behavior.

Kinematic hardening in large elastoplastic strain
Engineering Fracture Mechanics, 1985Abstract 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.
