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.

On kinematic hardening and large plastic deformations
International Journal of Plasticity, 1986The 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 ...

Expansion of a hole in a disk with kinematic hardening
International Journal of Mechanical Sciences, 1969Abstract A complete solution is obtained for the enlargement of a circular hole in a disk of initial thickness h 0 = αr n 0 , where α and n are constants, using Prager's kinematic hardening law with Tresca's yield function and its associated flow rule.

Kinematic hardening model for overconsolidated clays
Computers and Geotechnics, 2001Abstract 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 ...

Shakedown for systems of kinematic hardening materials
1995The paper deals with the shakedown of systems with kinematic hardening materials. Analytical, numerical and experimental methods to solve shakedown problems will be introduced and discussed. Some examples are treated with these methods. Comparison shows that the results of these methods are in good agreement.
