On generalized kinematic hardening theory of plasticity

Ingenieur-Archiv, 1975
An 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.

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 ...

Experimental Inspiration for Kinematic Hardening Soil Models

Journal of Engineering Mechanics, 2004
Traditional techniques for identifying yielding of soils in the context of classical elastic-plastic soil models are criticized. However, the extended use of such procedures starts to reveal the kinematic nature of the plastic behavior of soils. It is suggested that the experimental determination of stress response envelopes can provide an objective ...

Elastic-plastic memory and kinematic-type hardening

Acta Metallurgica, 1975
Abstract In this article it is proposed that the classical plasticity concept of kinematic hardening is much more general and descriptive of plastic deformation in metals than has heretofore been acknowledged. Furthermore it is shown how microstructural ideas involving dislocation micro-mechanisms do, when properly coupled to the classical continuum ...

An Assessment of Kinematic Hardening Thermal Ratcheting

Journal of Engineering Materials and Technology, 1974
Analytical comparisons are made between the thermal ratcheting response of a kinematic hardening material, a perfectly plastic, and an isotropic hardening material for a two-element assembly. Significant differences were found in the range of mechanical and thermal loading for which ratcheting occurred and the magnitude of the strain accumulation when ...

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.

Corotational Rates for Kinematic Hardening at Large Plastic Deformations

Journal of Applied Mechanics, 1983
To illustate the effect of the choice of corotational rates at large plastic deformations, expressions for the stresses developing in large simple shear are obtained in closed analytical form under the assumptions of a rigid-plastic material response and a Mises type isotropically and kinematically hardening constitutive model for two different ...
