摘　　要：基于Reddy高阶剪切变形理论和广义Krmn型方程,用双重Fourier级数展开法求得了四边简支带压电层功能梯度复合材料混合层合板的自由振动及动力响应的解析解,分析中考虑了组分材料热物参数对温度变化的依赖性,讨论了材料组分指数、温度变化和控制电压对固有频率及动力响应的影响。Based on Reddy's higher-order shear deformation plate theory and general von Krmn-type equations, analytical solutions for free vibration and dynamic response of simply supported functionally graded plates with piezoelectric layers subjected to piezo-thermo-mechanical loads are presented by using double Fourier series. Temperature-dependent material properties are taken into account. Effects of volume fraction index, temperature rise and applied voltage on natural frequencies and dynamic response of the plate are also studied.
