Kinematic hardening of trusses
Ingenieur-Archiv, 1987Polycrystalline materials are modelled using plastic trusses. The rods of the truss simulate the slip systems of a single crystal while the geometry of the truss controls the interaction between the different slip systems. For calculations of the evolution of the yield locus in the space of the nodal forces, i.e. in the generalized stress space, due to

Kinematic hardening of granular materials
Ingenieur-Archiv, 1990Some recently developed constitutive equations (yield function, loading criteria, flow rule) for kinematic hardening of granular materials are discussed and some relevant material dependent parameters are determined on the basis of test results.

On nonlinear kinematic hardening
Acta Mechanica, 1968Traditionally, the kinematic hardening assumption is used in conjunction with an assumption that the stress-strain curve for simple tension can be approximated by a bilinear curve. This paper generalizes the concept of kinematic hardening for the case when the stress-strain law is nonlinear. It is shown that although a yield condition of the form

Kinematic hardening and Bauschinger effect
PAMM, 2019AbstractThis paper studies a single crystal subjected to anti‐plane shear‐controlled load reversal within the thermodynamic dislocation theory. Numerical simulations of the governing equations demonstrate the size‐dependent kinematic hardening and the Bauschinger effect. Both are caused by the excess dislocations.

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.

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.

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.

General Kinematic-Isotropic Hardening Model
Journal of Engineering Mechanics, 1999This paper first points out that an evolution rule of the yield center without a motion component in the plastic strain rate direction leads to ratchetting, while an evolution rule with such a component motion leads to proportional material response. The paper then successfully tackles such a dilemma by proposing a general kinematic-isotropic hardening
