In this paper, sheet metal forming processes are simulated with a solid-shell finite element entirely based on the enhanced assumed strain (EAS) method. The solid-shell formulation involves a minimum set of enhancing variables, resulting in a competi... Read More about Sheet metal forming simulation using EAS solid-shell finite elements.
