Abstract

Transients in creep are of fundamental importance. They are commonly described either by a change in the isotropic strength of a material due to an increase in dislocation density or by a change in directional hardening, often described by a backstress. Here we look at transients as developed by load redistribution in Finite Element simulations. Two types of material models are used. The first contains grains with binary strength; the other uses grains with a continuous distribution of strengths. It was found that the load redistribution process is an important source in transient yielding and creep. An equivalent stress quantity to track the strength of a sample during deformation is proposed. Using this quantity a single load shedding curve can be obtained for both the tensile and creep tests. This unifies the material constitutive behavior for the very different boundary conditions seen in creep and constant-rate testing.
