金属学报(英文版)

Blank holder force(BHF) is an important measure to control the sheet metal forming.BHF is identified quickly using artificial network(ANN) on the basis of its analytical description.And critical rupture and wrinkle BHF curves are given.A close-loop control system is established to finish the forming process.
