Abstract
In this work the strain localization analysis of Hill’s orthotropic plasticity is addressed. In particular, the localization condition derived from the boundedness of stress rates together with Maxwell’s kinematics is employed. As done in previous works [1, 2, 3] for isotropic plasticity, the strain rate jump, defined as the difference in the strain rate fields between the interior/exterior points of the discontinuity (band) and characterized by Maxwell’s compatibility condition, has to be...
