Abstracts: Components press formed from layered or laminated metallic materials have Wide engineering application in aerospace, automobile, electrical, electronic and process industries. High strength ferrous material grades are widely used in automobile and aerospace application for improving strength to weight ratio. Forming of high strength material is difficult. Formability of high strength ferrous material can be improved by applying the layering of the higher formability materials. But to fabricate the layered\laminated blanks it-self is challenging issue. Further, metal forming mechanics of layered or laminated materials is complex to understand and under the circumstances, development of analytical models for studying and analyzing the forming mechanics of such materials is difficult. The aim of this study is to investigate the bending characteristics such as sheet thickness change and the bending angles of the sheet before/after springback. Share of high and advanced high strenght steels in automobile is increasing , however such a steel generally have a poor formability and high amount of springback because of discussed phenomena, it becomes difficult to control the dimension of the final product obtained using bending/forming. In this study, the results of analytical and experimental are compare with each other. According to that comparision, we will analyze the springback effect with bilayerd material (SS-304 and AL-6101T6) having combination of different dimensions.
