Die Shape Optimal Design in Bimetal Extrusion by The Finite Element Method

유한요소법에 의한 이중 금속봉 압출 공정의 금형 형상 최적설계

A new approach to die shape optimal design in bimetal extrusion of rods is presented. In this approach, the design problem is formulated as a constrained optimization problem incorporated with the finite element model, and optimization of the die shape is conducted on the basis of the design sensitivities. The combinations of the core and sleeve materials.
