Critical review of variable Young modulus in springback prediction during bending process

Abstract

Parts made from forming process are in huge demand in industries now a day. But while working with formed parts dimensional accuracy is the vital task. Dimensional inaccuracy is one of the main problems while working with the formed part which is due to springback. Springback is elastically driven event in which deform part change in dimension at the time unloading. So for better dimensional accuracy, springback should be predicted. During forming process many parameter are involving and all parameter should be consider for any metal forming analysis. During metal forming young modulus is one of crucial parameter which is change during forming process. Accurate prediction of springback is only possible when variable young modulus is considering. This paper deals with effect of variable young modulus on springback and its prediction model.
