Open AccessA very simple and general expression of the consistent tangent matrix for substep- ping time-integration schemes is presented. If needed, the derivatives required for the computation of the consistent tangent moduli can ...
Open AccessIn this paper, a new approach for powder cold compaction simulations is presented. A density-dependent plastic model within the framework of finite strain multiplicative hyperelastoplasticity is used to describe the highly ...
