【Abstract】 A new assumptions of extrusion center for defferent model stuff extrusion is presented. A theory about different modlle stuff extrusion is set up and develops corresponding software. The admissible velocity field and strain rate fields are simulated in this paper. The influences of area reduction, friction factor, and shape of dies are investigated. The theory is applied to different model stuff extrusion production.更多还原
