Abstract：

The double sides pressurized hydroforming process of metal sheet is numerically simulated by applying the commercial FEM software ANSYS/LS-DYNA.Using the ductile fracture criterion as the reference for judging the limit height of the process to put the necessary simulation results into the criterion.The simulation results of two materials under different initial liquid pressure represent that the limit height of the hydroforming could be boosted by increasing the initial liquid pressure,and the limit height could be boosted obviously when the initial pressure and the strength of the sheet are in the same rank.
