摘要
利用细观力学的Ｅｓｈｅｌｂｙ和ＭｏｒｉＴａｎａｋａ理论，考虑纤维与微裂纹之间的相互作用，预报了复合材料的有效热膨胀系数，研究了纤维体积份数、微裂纹密度对热力学性能的影响，为材料热应力分析提供了理论基础。
The Eshelby and Mori-Tanaka theories in micromechanics are used for considering the interaction of fibers and microcracks and predicting the effective thermal expansion coefficients of fiber composite materials. The effects of fiber volume fraction and microcrack density on the thermal mechanical behavior of the material are also studied. The developed method provides a theoretical basis for thermal stress analysis.
