| Abstract: | This paper analyzes the plastic deformation process of square shaped parts and the stress in the deformation area. Following the theory of slip line field, the area is divided into five sections and the distributing situation of the slip line in each section is analysed. Finally, the radius and the center of datum cycle and the mechanical model are deduced, which provids the basis for the determination of the dimensions of blanks of square shaped parts. |

| Keywords: | square shaped part slip line field mechanical model |
