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;    material parameters;
