Numerical Simulation of Hydrostatic Extruding Cu/Al Bimetal Clad through Equal-Strain Contour Concave Die

Abstract:

A bimetal composite material is a variant of the typical composite that is composed of two materials joined at their interface surface. The advantage of clad material is that the combination of different properties of materials can satisfy both the need of good mechanical properties and the demand of user such as electrical properties simultaneously. This paper is concerned with the hydrostatic extrusion process of copper-clad aluminum rod. The commercially available finite element program ANSYS was used to simulate the process of hydrostatic extrusion for Cu/Al bimetal composite through the equal-strain contour concave dies. The relative slippage between the inner and outer metals under the condition of different friction factors is studied, and the stress-strain distribution in the billet was analyzed. Experiment test was carried out; it was found that the experimental result has good agreement with relative slippage from the finite element analysis.
