Deformation behavior of circular tubes during free hydraulic bulging was studied. Initial thickness deviation in tube periphery affects the deformation. Deformation of aluminum alloy tube and copper tube was investigated by FEM simulation and experiment. In the FEM simulation, which is based on dynamic explicit method, bulging speed was controlled by the amount of pressure medium in the tube. This volume control method of the pressure medium was easier than pressure control method to get the maximum pressure that can load on the tube. It was clarified that increase in thickness deviation during the free bulging depended on tube material and boundary condition at the tube ends.
