A metal sheet stamping simulation promises improved car part production

May 13, 2019 / Phys.org

The process of stamping metal sheets to create parts used in automotive products such as car doors has received a virtual upgrade in the form of a simulation method devised by Kanazawa University-based researchers. Their simulation can be used to optimize a metal stamping press in its conceptual design stage, thus reducing the costs of physically trialing designs. This method is not only cost-effective, but also more comprehensive than past simulation methods.
To improve fuel consumption, automotive manufacturers have increasingly been looking to fabricate cars using lighter materials than traditional steel. High-strength steel is considered a lightweight alternative, but when sheets of high-strength steel are stamped into shape to fabricate car parts, they are more likely to bend, tear, wrinkle, or become too thin in places compared with parts made of traditional steel.
