A thermodynamically consistent theory of stress-gradient plasticity

As an extension to strain-gradient models of size-dependent plastic behaviour, this work proposes a model for stress-gradient theory. The is distinguished from earlier works on the topic by its being embedded in thermodynamically consistent framework. development carried out context single-crystal plasticity, and draws conventional plasticity. explored numerically using example torsion thin wire comprising face centred cubic crystal, behaviour compared with that based recent disequilibrium density
