418 Uniaxial tension/compression of superplastic material behavior described by particle sliding constitutive law

Abstract

Meso-mechanical material modeling of super plastic metal alloy is attempted. Multi-crystal grains in the metal that exibit extensive surface sliding is modeled by setting a tangential spring layer between the grain and the matrix. The constitutive law for the domain in which mult-phase crystal grains of the type are dispersed is derived with the use of equivalent inclusion method on the basis of self-consistent shceme.
