Abstract

The hot tensile test of BR1500HS ultrahigh strength steel was carried out on Gleeble3500 thermo-mechanical simulator. The process was predicted by finite element simulation based on Freudenthal fracture criterion. Then, the Freudenthal fracture criterion is modified based on the relationship between the Freudenthal fracture criterion and fracture threshold with deformation conditions. The modified fracture criterion was applied to the DEFORM software, and the results show that the modified Freudenthal fracture criterion has high accuracy and can be used to predict the damage and fracture of BR1500HS.
