Springback or elastic recovery refers to the shape discrepancy between the fully loaded and unloaded configurations. Springback causes changes in shape and dimensions that can create major problems in the assembly. Hence, prediction of the springback is an important issue in sheet metal forming. Various investigations of springback prediction show that process parameters such as bend radius, sheet thickness, tool geometries, punch speeds, and material properties have considerable influence on springback. In the present paper, the effect of sheet thickness, punch speed and material properties on the springback angle has been discussed. Two different approaches, implicit and explicit are considered. A strain rate dependent plasticity model has been used to determine the effect of punch speed on the springback angle
