Abstract: A math formula about the relation between fluid pressure after overflowing and punch stroke that can be applied in general FEM software was proposed. It is proved that theoretical results keep coincident to experimental results and the method to simulate hydrodynamic deep drawing process that integrates general FEM software with mathematical description is feasible.
Key words: hydrodynamic deep drawing; fluid pressure; FEM
