    • Other recent work relates the rate dependence and nonlinearity of strain hardening to an Eyring-like model in which the activation volume V decreases with increasing strain. In contrast, we predict that V increases. An important difference between the approaches is that in the Eyring-like models, V is a parameter with the dimensions of volume rather than a physical volume
