On the role of moving elastic-plastic boundaries in strain gradient plasticity

Research output: Contribution to journalArticleAcademicpeer-review

Abstract

Gradient plasticity theories which are used to describe size effects require nonstandard boundary conditions. We believe that the role of these boundary conditions in combination with a moving elastic–plastic boundary has so far not been well understood. In order to clarify the conditions which are required at such an internal boundary, semi-analytical solutions are derived for a foil in pure bending. Two variants of gradient theories are considered, for which the necessary conditions are significantly different.
