A non-associative orthotropic plasticity model for paperboard under in-plane loading

In this paper, we present an in-plane yield criterion using sub-surfaces that are related to the orthotropic material axes of paperboard. A non-associative flow rule is proposed to decouple the plastic volumetric strain response from the yield surface’s shape. This offers adaptability of both, the y...
