Springback Prediction of the TRIP Sheet Steel Stamping

Abstract:

Article Preview

An enhanced elastic-plastic constitutive equation taking into account strain induced transformation is developed. The variation of the Young’s modulus with the martensitic transformation during stamping process is also introduced to improve the accuracy of springback simulation for TRIP steel. The accuracy of the proposed method is verified by comparing with the conventional FE model and experimental results. The enhanced material model is testified to be efficient in accurate prediction on springback for TRIP steels, which will put forward the application of TRIP steel sheet in auto body manufacturing.
