Abstract

The inelastic behavior of powder metals is significantly influenced by hydrostatic stress. In this paper a unified theory is proposed that captures not only such time-dependent phenomena as creep, stress relaxation and rate sensitivity but also demonstrates a sensitivity to hydrostatic stress. The theory is developed from a dissipative potential function, which assures the inelastic boundary value problem is well posed with unique solutions. © 1988.
