This study aims to investigate quantitatively the springback characteristics of the several steel sheets including high-strength steel (HSS) sheets through experiment and finite element analysis (FEA). Some of the materials used are coated and the others not. The geometric springback parameters in the U-draw bending test, one of the NUMISHEET '93 benchmark problems, are measured or calculated for various levels of the blank-holding force.
