TOA Industries successfully controls springback in thin ultra-high strength steel stamping parts using PAM-STAMP 2G

To develop Ultra-High Strength Steel automotive components in a short period of time, early assessment by digital simulation is essential and its accuracy is crucial. PAM-STAMP 2G, which is highly accurate in springback analysis, can be used to combine the Yoshida-Uemori material model with the Bauschinger effect in order to further improve springback prediction accuracy.
Challenge
There is a strong pressure to reduce CO2 emissions in vehicles, one way being to cut their weight. At the same time, crash performance must not be sacrificed. The usage of thin ultra-high strength steel can solve both these problems. One of the complexities that arises when using ultra-high strength steel is the high risk of springback during stamping.
Traditional simulation methods for mild steel show their limitations here, so the Yoshida-Uemori model has to be used to control the springback.
Benefits
TOA Industries has found that by using PAM-STAMP 2G in combination with the Yoshida-Uemori model, the springback for thin ultra-high strength steel parts can be controlled within the normal time frame and at a low cost. They now mass-produce 980MPa-class ultra-high strength steel components used in current vehicles.
