Increased application of high strength steel sheets to automobile bodies is a practically effective means to reduce body weight and to enhance the fuel mileage of automobile, which meet the social requirement of decreasing loads on the global environment. Although the reduction of body weight without sacrificing collision safety can be attained by applying steel sheets of high strength to the bodies, this type of sheets may result in forming problems such as fracture or spring-back during sheet forming. This article reports Finite Element Method (FEM) analysis, which has been successfully applied to clarify energy absorption during collisions, formability of tailor-welded blanks and spring-back behavior of high strength steels used for automotive body parts. The analysis results, i.e, the estimation of strain or strain-rate of body parts during collision, fracture or spring-back during forming, contribute to the improvement of forming process and the development of high strength steel sheets.
