Springback in Sheet Metal Forming

  • Dr. Gawade Sharad, Dr. V. M. Nandedkar

Abstract

One of the most sensitive features of the sheet metal forming is the elastic recovery during unloading called springback. Sheet metals are prone to little or more amount of springback depending on elastic deformation. Obtaining the desired size and shape of the component and also the design of die depends on the knowledge of the amount of this spring-back. So the accurate prediction of the springback is very important. The springback is affected by the factors such as sheet thickness, material properties, tooling geometry etc. In this paper the effect of various parameters such as sheet thickness, ratio of die radius to sheet thickness, strength coefficients on springback are studied for three different materials namely IS513D, DP600-HDG and 5182 Aluminum by using FEA.
