Thermalization of plastic flow versus stationarity of thermomechanical equilibrium in SGR theory

Abstract

1 Here U = kBTgu is the activation energy of unstrained zones. In general their activation energy is A(u, ǫ el ) = −E (u, ǫ el ). Note that while SGR theory does not incorporate the quasiuniversal A ∝ (δ − |ǫ el |) 3/2 proportionality identified by more recent work [28,29,30], it can in principle be modified to do so.
