Abstract
The stamping formation modes of sheet metal,the relationship of the modes' conversion rule and the classification of the formability based on the different fracture's unsteady patterns were described.The simulating formability test methods such as the approximating method of simplifying non-cylindrical project to partial cylinder,the simulating-profiling method for the deformation and shape of projects,and the method of reducing project's dimension scale were proposed.There were three basic modes for the designing the simulating formability tests.Furthermore,various kinds of current test methods of sheet metal formability were analyzed,which could be used as the basis of selecting and applying test methods for revising GB/T 15825《Sheet Metal Formability and Test Methods 》.
