本文研究了短纤维/晶须增强单向复合材料在弹塑性变形过程中增强尺度的细观力学行为。将等效夹杂法推广到含长径比可变的纤维/晶须复合材料体系。引入了基体材料的流动规律，使复合材料的多轴变形问题得以处理。理论预测报告的影响，可变纤维的纵横比，加载方向，和静水应力的复合材料的宏观行为和应力状态的增强规模。
This study examined the micromechanics at the scale of reinforcement in a short fiber/whisker reinforced unidirectional composite undergoing elastic/plastic deformation. The equivalent inclusion method was extended to consider composite systems comprising fiber/whisker of variable aspect ratio. The flow rule of matrix material is incorporated such that the composite deformation involved multiaxial loading can be handled. Theoretical predictions are reported on the effects of variable fiber aspect ratio, loading direction, and hydrostatic stress on the macroscopic behavior of the composite and the stress state at the reinforcement scale.
