Simulation of springback and wrinkling in stamping of a dual phase steel rail-shaped part

摘要

The prediction of part defects in sheet metal forming by numerical simulation allows the automotive makers to reduce the costs of designing tools and to shorten the time-to-market cycle. The research is focused on improving the predictability of springback and wrinkling occurrence by using the static explicit finite element simulation of stamping a dual phase rail part. The proposed solution for simulation includes algorithms implemented in the finite element code which make possible the obtaining of more accurate prediction results.
