摘要
研究了短纤维／晶须增强金属基复合材料在弹塑性变形中的应变分布，得到了增强体与基体应变的统计规律，提出了短纤维／晶须增强金属基复合材料的材料模型，导出了相应的弹塑性本构关系，预测了硼酸铝晶须增强Ａ１基（［ＡｌＢＯ］ｗ／Ａ１）复合材料单轴拉伸应力应变关系，结果与实验吻合良好．
Aimed at metal matrix composites reinforced by short fiber/whisker, a material model is proposed. Based on the statistical description of strain distribution in reinforcer and matrix, the elasto-plastic constitutive relation of short fiber/whisker reinforced aluminum matrix composites is derived. The tensile stress-strain curve of [AlBO](w)/Al composites is predicted, and the result is agreement well with the experimental one.
