摘要
采用平面应变有限元方法研究了晶须转动对晶须增强铝基复合材料热压缩变形行为的影响.数值结果表明:晶须转动不仅引起晶须承载能力的下降,而且也影响基体的塑性变形行为,同时复合材料在热压缩变形过程中表现出明显的应变软化行为.数值分析研究进一步证明:晶须转动是复合材料出现应变软化的重要原因.
The effect of the whisker rotation on the hot compressive deformation behavior of the whisker reinforced aluminum matrix composite is investigated by the plane strain finite element method. Numerical results show that the whisker rotation induces a reduction in the whisker carrying load ability and influences the plastic deformation behavior of the matrix. Meanwhile, the composite exhibits significant strain softening during the hot compression. It is proved that the whisker rotation is an important reason for the composite softening.
