【Abstract】 This paper analyzed the hygrothermal influence on the mechanical properties of the fiberreinforced,symmetrical cross-ply composite plates from the point view of micro mechanics of the composite 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.更多还原
