Memory of Stress History in Single and Two Surface Plasticity for Granular Soils
ABSTRACT Recent studies have identified limitations in Manzari and Dafalias' 1997 and 2004 sand plasticity models, particularly regarding one‐way unloading/reloading and ratcheting loading modes. These models are widely accepted as bounding surface models in the geotechnical engineering community; thus, concerns have arisen about a fundamental lack of ...

The Bauschinger Effect in a High-Strength Steel
The object of this work was to evaluate quantitatively the Bauschinger effect in a 4330 modified steel as a function of strength level and structure as derived from variations in heat-treatment.

The strain bardening hypothesis assumed exerts a certain influence on the shakedown of the structure. In the present paper the problem is reduced to an analysis of the influence of the Bauschinger effect on the shakedown process.

Finite element simulations of deep drawing of commercially pure titanium sheets using single‐radius and varying‐shoulder‐radius dies are conducted. Two types of nonassociated flow rules are applied, and the results are verified by comparing them with the experimental results.

Bauschinger Effect Prediction in Thick-Walled Autofrettaged Cylindrical Pressure Vessels
The paper addresses the Bauschinger effect under complex stress state in materials with deformation-induced anisotropy whose strain hardening is described by the isotropic–kinematic (translational) type hardening hypothesis.

Study of Bauschinger effect in various spring steels
grantor: University of TorontoIt is recognized that the effective life of automotive suspension springs could be ended by yielding rather than fracture. The industry describes this problem as load loss or sag.

ABSTRACT In this study, a material constitutive model based on the memory surface concept was proposed to reproduce the cyclic hardening and softening behaviors of SN490B structural steel under constant strain amplitude loading. The model incorporates combined isotropic and kinematic hardening rules, with strain‐amplitude‐dependent formulations ...

Understanding long range internal stresses (LRIS) may be crucial for elucidating the basis of the Bauschinger effect, plastic deformation in fatigued metals, and plastic deformation in general.
