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.

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.

Kinematic-Hardening in Zinc-Alloy Tubes

Journal of Applied Mechanics, 1965
The kinematic theory of strain-hardening is used to evaluate the post-yield behavior of tubular specimens subjected to axial force combined with internal pressure or torque. Prediction of yield-surface motion during strain-hardening is simplified through the use of piecewise linear yield criteria.

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.
