摘要：

The effects of forming damage are analyzed, which occur during hot stamping process, on the load-carrying capacity and failure mode of hot stamped beams. A damage-coupled pre-forming constitutive model was proposed, in which the damage during hot stamping process was introduced into the service response. The constitutive model was applied into the three-point bending simulation of a hot stamped beam, and then the influences of forming damage on the load-carrying capacity and cracks propagation were investigated. The results show that the forming damage reduces the maximum load capacity of the hot stamped beam by 7.5%. It also causes the crack to occur earlier and promotes crack to propagate along the radial direction of the punch. © 2020 Journal of Beijing Institute of Technology
