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 ...

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 ...

Expansion of a hole in a disk with kinematic hardening

International Journal of Mechanical Sciences, 1969
Abstract 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.

On nonlinear kinematic hardening plasticity theory

Nuclear Engineering and Design, 1974
Abstract Experimental data for metals, e.g. stainless steel, at elevated temperatures show that the loop of the stress-strain curve obtained in a cyclic tension test grows in size in a bounded fashion with each successive cycle. This implies that either the material follows isotropic hardening during its initial deformation phase from the virgin ...

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.

Shakedown for systems of kinematic hardening materials

1995
The 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.

General Kinematic-Isotropic Hardening Model

Journal of Engineering Mechanics, 1999
This 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

Kinematic hardening rule in single crystals

International Journal of Solids and Structures, 1979
Abstract Based on the theories of Seeger's dislocation pile-up and Orowan's dispersion hardening, the hardening behavior of single crystals was found to obey Prager's kinematic hardening rule. Under single slip, yield surface moves along its normal while under multislip it moves along the direction of incremental stress.
