Practice-relevant simulation of hydroforming is used to check and optimize metal forming processes and to determine their feasinbility before expensive tools are manufactured. FEM simulation improves the understanding of the process and serves as a tool for process planning. Besides the fundamental questions within the scope of feasibility studies, other special targets of simulation are the material flow and the use of the deformation capacity of the material used for manufacturing hydroforming parts. The matching of calculated values and those determined in experiments, especially during the intermediate stages of the metal forming process, including preforming, is necessary to understand the hydroforming theoretically.
