N2 - To intensify the use of implicit finite element codes for solving large scale problems, the computation time of these codes has to be decreased drastically. A method is developed which decreases the computational time of implicit codes by factors. The method is based on introducing inertia effects into the implicit finite element code in combination with the use of iterative solvers. Another advantage of introducing inertia effects into an implicit finite element code is that it stabilizes the computation, especially when the problem is under-constrained. The dynamics contributions are successfully implemented for both the plane strain element (only displacement d.o.f.) and the Mindlin shell element (displacement and rotational d.o.f.). Deep drawing simulations are performed to investigate the performance of the dynamics contributions in combination with iterative solvers. It is concluded that the computation time can be decreased by a factor 5–10.
