Deformation and stress analysis of galvanized-annealed steel JAC390W using AUTOFORM

Abstract

In the automotive industry, parts are produced mostly by stamping the part with the help of die and punch. During the mass production of the part where heavy punch machines are involved, various defects like spring-back, wrinkle, thinning, etc can occur FEM simulation can be performed to identify and reduce the defects at the early stage. In the present work, surface analysis of a front seat panel is carried out on AUTOFORM R7. The purpose of this research is to study the effect of change in sheet thickness and blank holder force on wrinkle and spring-back during forming. Forming Limit Diagram is studied for limits to forming. The methodology can be implemented to design automobile components in the future.
