Abstract:

The task of computer simulation of combining of static loading and impulse loading under forming of sheet metal by mobile medium with using LS-DYNA was resolved. The computational procedure is used for calculation of parameters of process of stamping of a part “diaphragm” from thin sheet an aluminum alloy. Results of computer calculations together with formability diagram have allowed defining of the combined loading parameters for stamping the part without destruction of sheet metal.
