| Abstract: | A method for measuring internal pressure distribution on a cold extrusion die by photoelastic experiment is described.Based on the above measurement,a die is de- signed by FEM-optimuming process and verified by photoelastic experiment.This synthetical analysis will enhance die bearing capacity and improve die design as well as economize die materials. |
