Springback is a common phenomenon in sheet metal forming,caused by the elastic redistribution of the internal stresses during unloading.The mechanism of springback has been discussed.Based on the explicit to implicit sequential solution method to simulate springback,the factors infecting springback have been compared,that include material property,friction coefficient,thickness,etc.It is significant in practice to make reasonable forming techniques,in the process of springback compensation for design of tools, reduce springback,improve parts' precision.
