The calculating results are compared with the test data in available literatures and FEM results. The research results show that the plastic hinge model is precise and correct, which can satisfy with the actual engineering demands. The collapse pressure of perforated liner casing decreases with phrase angle, initial ovalization and diameter-thickness ratio increasing, and increases with the yield stress. The phrase angle and initial ovalization have greatly influence on the collapse pressure. The collapse pressure of perforated liner casing is slightly changed with the diameter and density of perforation when the diameter and density are smaller than 12mm and 120 shots per meter, respectively.
