摘要：

The crack behavior and bending deformation of pre-cracked sheet are coupled under the pressure loading. Two theoretical methods (SCMLD and PTELD) were used to compare and verify the bulge test data of intact aluminum alloy sheets, and the applicability of the two methods in equilibrium bulge test were discussed. ABAQUS extended finite element method (XFEM) and the parameters of fracture energy based on experiments were used to simulate the bulging deformation and failure behavior of pre-cracked sheet, the results agreed with the experimental test data well. What is more, the slope of h - p curve reflects the equivalent bending stiffness, which is affected by the crack shape length rather but not the crack shape.
