A new Finite Element Technology for the Numerical Simulation of High Speed Forming Processes

Abstract

In this contribution we propose a new solid-shell element formulation based on the concept of reduced integration with hourglass stabilization. Due to the absence of shear locking thin structures can be computed with only one element layer over the thickness. This enhances the computational efficiency in two ways. First of all the number of elements is reduced. Secondly, working with an explicit scheme, a larger critical time step is obtained. The damping and the mass matrix are not affected by the element technological treatment. The formulation is validated at first by typical element examples as well as two forming simulations.
