摘　　要：基于Reddy高阶剪切变形板理论 ,用双重Fourier级数展开法求得了材料物性参数受湿热环境影响的四边简支纤维增强正交铺设层合剪切板的自由振动及动力响应的解析解 ,并讨论了湿热环境及纤维体积含量对固有频率及动力响应的影响。Based on Reddy's higher order shear deformable plate theory,analytical solutions of free vibration and dynamic response for simply supported fibre reinforced cross ply shear deformable laminated plates subjected to transverse dynamic loads and in hygrothermal environments presented by using double Fourier series.The material properties are affected by hygrothermal environments.Effects of hygrothermal environments and fiber volume fraction on natural frequency and dynamic response are studied.
