Abstract�� Springback is an inevitable phenomenon in sheet metal forming process. As an effective method to solve springback problem, numerical simulation is receiving increasing attention throughout industry and academic world. Integrated springback simulation can be divided into two steps, that is punch loading forming process simulation and punch unloading springback process simulation. The quasi-static implicit approach and dynamic explicit approach in springback simulation are described, and their advantages and disadvantages in computing springback problems are compared. A FEM model for punch loading forming process simulation and punch unloading springback process simulation is introduced and a computing example using software developed by authors is given.
