F-40 Numerical simulation of hot stamping of quenchable boron steel

摘要：

Quenchable boron steel is a new type of ultra high strength steel used for automotive parts to reduce the weight of automobiles and maintain the safety requirements. On the basis of experimental data of mechanics and thermal physical properties, a material model under hot stamping condition of quenchable steel was set up, and the numerical simulation to the whole hot stamping process of hot forming，quenching and spring-back of bending parts was made with ABAQUS software. The results show that the springback of hot stamping parts increases when blank holder force (BHF) decreases; and it increases when the clearance between punch and dies increases and when the die radius increases. The simulation results are basically in agreement with experimental results.
