1. Viscoplastic behavior
1.1 Norton-Hoff law of viscoplastic behavior
From a physical point of view, plastic flow stress depends on the strain rate when hot, since dislocation displacement is thermally activated, which means that it also depends on temperature (see figure 9 in
The simplest generalization of the tensile results is to assume that the plastic flow stress σ 0 evolves like the tensile stress and depends only on ,...
