A method for determining the internal stress based on zero entropy of activation

Abstract

Attempts to present an alternative basically different approach for determining internal stress. Points out that this requires that it be possible to approximate the temperature and strain rate dependence of the effective stress by a power law, that the associated experimental data be obtained at temperatures low enough to avoid the effects of dynamic strain aging and that information be available about the temperature dependence of the modulus. Concludes that the simple technique outlined may have some real advantages for determining internal stress and for modeling the flow stress and strain rate sensitivity as a function of temperature and strain rate under certain conditions.
