STUDY ON WARM FORMING LIMIT PREDICTION OF ADVANCED HIGH STRENGTH STEEL DP780 SHEET METAL
In order to accurately predict the forming limit curve of DP780 steel sheet under the condition of warm forming,the ductile fracture prediction model was introduced into the numerical simulation. Based on the unidirectional tensile test results analysis of DP780 steel sheet in the temperature range...
