摘　　要：依据复合材料细观力学研究了纤维增强正交各向异性复合材料层合板的力学性能与温度和湿度的关系,在宏-细观力学模型框架下建立了考虑湿热效应的屈曲控制方程,分析了温度和湿度对复合材料层合板在面内压缩载荷下屈曲行为的影响,并讨论了不同边界条件对屈曲载荷的影响.This paper analyzed the hygrothermal influence on the mechanical properties of the fiber- reinforced, symmetrical cross-ply composite plates from the point view of micro mechanics of the compos- ite materials. Governing equations for the buckling of the plates subjected to the in-plane loading under the hygrothermal environment are educed using the macro-micro analytical approach. Variations of the critical loads with respect to the changing of the temperature and the moisture are obtained. The effects of the boundary conditions on the buckling loads are discussed.
