Abstract

The effects of friction coefficient on formability behavior of advanced high-strength steel sheets have been examined in this study. For this purpose, forming analysis has been conducted by stretching the three different steel sheets such as DP600, DP800 and DP1000. Forming processes have been done by using punch that has different friction coefficients (0.05, 0.15, 0.3, 0.6 mu) in nakajima forming die. As a result of the analysis, it has been observed that thinning amount and forming force have increased by the increasing in the friction coefficient. When major and minor deformations on the sheet have been examined, it has been determined that the increasing friction coefficient makes plastic deformation amount increase.
