摘要
对塑性细观力学模型的割线模量法、各向同性化的切线模量法、各向异性化的切线模量法和弹性约束法的适用性及预测结果进行了分析比较表明，在变形较小的情况下各向异性化的切线模量法能较好地预测复合材料的拉伸和循环硬化性能，各向同性化的切线模量法和割线模量法较适用于对单向拉伸的预测，而弹性约束法的预测则偏高．
Micromechanical models bed on the Mori-Tanaka mean field theory are studied in detail for predicting the tensile and cyclic behaviors of composite materials. The validity of the models is discussed in the light of the results of comparison with the experiments. The anisotropic tangent moduli method gives satisfactory predictions both for the tensile and cyclic hardening of the composites, and the isotrpic tangent moduli method and secant moduli mechod are suitable for the tensile hardening predictions, the elastic conshaint model seems to give overestimates for both situations in hardening.
