摘要 基于大变形弹塑性有限元理论,采用ANSYS有限元程序,通过建立合理的有限元分析模型,对Cu/Al双金属复合材料静液挤压固相结合的非稳态过程进行了数值模拟研究,得到了变形体在挤压过程中的等效应力、应变分布及相对滑动量随摩擦系数的变化情况,揭示了组元金属在静液挤压成形过程中的流动规律,指出在一定的变形量条件下,增大内外层金属之间的摩擦系数是较好实现内外层金属固相结合的主要方法。

Abstract:Based on the large deformation elastic-plastic finite element method(FEM) theory and finite model,the process of solid phase bonding for Cu/Al bimetal composite by hydrostatic extrusion was analyzed by ANSYS FEM with frictional elements inserted between two contacting metals.The varying order of relative slippage between inner and outer metal along with friction coefficient were obtained.The distributions of the equivalent stress and the equivalent strain in the sample on the process of binding by hydrostatic extrusion were also achieved.The flowing laws of component metal on the deforming process of hydrostatic extrusion were opened out.The computational results are close to those obtained by experiments.The conclusion is that increasing friction coefficient between inner and outer metal is the main effective method to bond bimetal material.
