摘要：
In this study, a U-channel bending test with tension were used to evaluate the surface damage resistance of dual-phase (DP) steel against heat treated Mo-Cr cast iron, and a numerical simulation model of the U-channel bending were developed to analyze the interface contact pressure on formed part that is an important influencing factor of surface damage. Investigation results for two bare steel sheets DP780 and DP590 demonstrate that DP780 steel showed more severe surface damage on formed part, and that for the steel DP780 greater interface contact pressure is induced as a result of effect of larger plastic deformation.
