Abstract: In the simulation of hot forming of high-strength steel, the phase transformation process can be simulated using current commercial finite element analysis software; however, the forming damage process can not be simulated. To overcome such problem, a damage-phase transformation constitutive model for high-strength steel hot forming is established. By writing user defined material subroutine of this mechanical model, which is used in LS-DYNA software, the phase transformation process and forming damage process can be simultaneously predicted. Furthermore, hot forming virtual test of cap-shaped parts is conducted. Results show that the maximum value of the volume fraction of martensite appears in the flange portion of the cap-shaped parts, the average volume faction is 98.5%; while the maximum forming damage concentrates in the middle of the side wall of the parts, and its value reaches 0.7. The effectiveness of constitutive model is verified in this test, and this research may provide guidance for actual production of hot forming of high-strength steel.

Key words: solid-state mechanics, damage-phase transformation constitutive model, high-strength steel, hot forming, numerical simulation
