In this paper, some of the most important criteria of metal forming process are analyzed and studied. Frequently, work piece material is not sufficiently malleable or ductile at ordinary room temperature, but may become so when heated. Thus, we have both hot and cold metal forming operations
Metal Forming, Plastic Deformation, Yield Criteria, Stress Tensor
