Journal ArticleDOI
A mathematical representation of the multiaxial Bauschinger effect
C. O. Frederick,Peter Armstrong +1 more
TL;DR: A mathematical representation of the multiaxial Bauschinger effect of materials at high temperatures was presented in this paper. But the model was not considered in this paper, nor in the paper.
Journal ArticleDOI
Constitutive equations for cyclic plasticity and cyclic viscoplasticity
TL;DR: In this paper, the cyclic constitutive equations developed and used at ONERA and LMT-Cachan are presented in detail in terms of a hierarchy of various models, including the Ohno-Kachi time-independent plasticity theory, two unified viscoplastic models by Walker and by Krempl and Yao, the new developments of the endochronic theory by Watanabe and Atluri.
Journal ArticleDOI
A review of some plasticity and viscoplasticity constitutive theories
TL;DR: In this paper, the main ingredients and assumptions of developing macroscopic inelastic constitutive equations, mainly for metals and low strain cyclic conditions, have been discussed, with some comparisons with the previous ones, including more recent developments that offer potential new capabilities.
BookDOI
Unified constitutive equations for creep and plasticity
TL;DR: In this paper, Hart's Model for Grain Matrix Deformation was extended to a multiaxial loading case and a new state variable theory was proposed to describe the effect of grain boundary sliding.
Journal ArticleDOI
The stress and temperature dependence of steady-state flow at intermediate temperatures for pure polycrystalline aluminum
TL;DR: In this article, the activation energy for steady-state creep (Qss) was found to be equal to about 87 kj mole−1 which corresponds quite closely to the activation energies for dislocation pipe diffusion as measured by Volin, Lie and Balluffi using a void shrinkage analysis.
