[Case Study] Application Case Series 1 of Plastic Processing Simulation - Deep Drawing Process

This analysis example introduces a drawing process for a corner box-shaped container.

**Case Overview** ■Product Name: NX Nastran ■Analysis: Nonlinear Static Analysis ■Industry: Mechanical Components Plastic processing primarily involves forming processes that include contact between tools and workpieces. Among these, the method of forming bottomed containers from metal sheets using a punch and die is called deep drawing. Various factors such as the structure and material of the mold, the shape of the blank, and friction conditions influence the process, resulting in changes in the stress distribution in different parts of the blank during forming, leading to issues like cracking and wrinkling. This analysis example introduces a deep drawing case of a rectangular box-shaped container. The initial shape of the blank is 200x200 with a thickness of 0.82mm. The die is a rigid flat plate with a square hole measuring 102.5x102.5 with rounded corners of 10mm radius. The punch is a rigid body with a size of 100x100 and has steps, and similarly, the wrinkle suppressor is also a rigid flat plate. □ For other functions and details, please refer to the catalog.
