Abstract
In the present paper the performance of a newly developed reduced integration solid-shell element based on reduced integration with hourglass stabilization is studied in the field of sheet metal forming. The element acts together with a material model including combined isotropic/kinematic hardening with extension to yield anisotropy. Considering the well-known s-rail problem an excellent agreement with experimental results for the punch force has been obtained. Further the final geometry after springback is considered. A good correlation to the experiments has been achieved. A second example investigates a circular deep drawing process of an anisotropic sheet metal. The earing contour of the fully drawn cup was predicted very well.
