Abstract
A method for simulating a hydroforming process includes modeling a virtual hydroforming die and a virtual tubular workpiece. The virtual workpiece is placed within the die after the die has been expanded. The die is then contracted to a finished size while the workpiece is deformed into a non-circular cross section in contact with the virtual die. The workpiece is subsequently pressurized to simulate production of a finished part.
