The shaping by hydroforming process involves several complex phenomena and presents several types of nonlinearities (geometric, material,...). The development of a hydroforming operation requires a lot of testing to determine with precision the optimum loads of trips and get a room without defects. Advances in digital tools have enabled manufacturers to simulate and optimize their production facilities before launching the production in order to minimize the maximum rate of defective parts.doi:10.1051/matecconf/201928604001 fatcat:hfbtbarmyvbcznqdhd3lrxwwiq
