Abstract
This paper aims at presenting an efficient computational tool for magnetic pulse forming processes. This too - based on the coupling between the FORGE® thermomechanical solver and an electromagnetic module - is then applied to investigating a test case provided by the I2FG Group for benchmarking purposes. Comparisons carried out between the results obtained using a quasi-static constitutive law with one taking into account the dynamic behaviour of the material emphasize the sensitivity to dynamic material behaviour – and thus the need for carrying out material behaviour identification for strain rates close to the ones experiences by the material in such processes.
