The basic assumption of the slip line method is that the thickness of the sheet flange is constant and in the plane strain state, the material is isotropic, no hardening, and the influence of the friction force distribution on the plastic flow is not considered. There are three common basic methods. The method is mainly based on some empirical calculation formulas, so its application range is affected, and it is mainly applied to expandable stamping parts with simple shapes (such as rotating parts, curved parts, or stamping parts composed of these simple shapes). In general, the method of developing the free-form surface of the plate type by experience is a method of ambiguity, and its accuracy is affected by many factors such as the richness of the user experience, the empirical formula used, and the selection of specific process parameters. Its accuracy needs to be further improved.
