Abstract：

Based on the mechanical model in reference, the paper proposes the fracture criteria for bottom and wall areas of the rectangulow part, and the calculating formulae for limit blank holding force(BHF) using diffuse instability theory and the assumption of ply-anisotropy. A calculation example is presented in this paper, and the result is also discussed.
