摘要

The friction test with hot-dip galvanized high strength steel sheet was conducted under various contact pressures, to investigate the influence of contact pressure on frictional behavior of steel sheet. According to the test result, the contact pressure effect on friction is considerable. The friction between tool and work-piece influences the stress distribution during stamping process. To investigate the influence of frictional behavior on stress distribution at stamped part, the U-draw bending under constant blank holding force with different blank size were conducted. As the result of study, the variation of frictional behavior depending on contact pressure results changes in the stress distribution of parts that has effects on tendency of springback for high strength steel sheet stamping.
