摘要
Wrinkling and tearing occur more easily for high strength steel(HSS) than common steel during sheet metal forming. Simultaneously, the tendency of dimension and shape imprecision is more significant. One of the major methods improving the formability of HSS is the variable blank-holder force. Based on the numerical simulation and orthogonal design of experimental analysis methods, the formability of HSS was investigated through analyzing the variant depth box drawing under varying the binder force profile s...
