Identification of material parameters for springback prediction using cyclic tension–compression test

In sheet metal forming process, springback is a critical problem for die makers, particularly in case of advanced high strength steels. Therefore, FE simulations were often used to calculate materials deformation behavior and the springback occurrence of formed sheet metals. Recently, the Yoshida–...

Sep. - Oct. 2016 1. Introduction At present
production of automotive components have become very high competitive. Thus
part manufacturers require shorter time for developing dies. Besides
more accurate methods are needed in order to improve the quality of produced parts. For current automotive parts
advanced high strength (AHS) steel grades have been continuously introduced and employed so that both lightweight and higher strength characteristics are fulfilled. However
one great challenge of AHS steels in the forming process is the springback effect. It
