摘要 基于Reddy高阶剪切变形理论和广义K偄rm偄n型方程,对热环境中功能梯度材料剪切板屈曲后的自由振动进行了分析,分析中同时考虑材料热物参数对温度变化的依赖性及热传导.数值算例给出均匀和非均匀温度场中功能梯度材料剪切板在轴向压缩荷载作用下的振动特性,并讨论了材料组分指数、温度场等参数变化所带来的影响. This paper presents free vibration analysis of postbuckled FGM plates in thermal environments based on Reddy’s higher order shear deformation plate theory and yon Karman-type equation. Heat conduction and temperature-dependent material properties are both taken into account. The numerical illustrations are conducted on vibration characteristics of postbuckled FGM plates subjected to uniaxial compression under uniform and non-uniform temperature fields. The effects of volume fraction index, temperature changes on vibration characteristics are discussed in detail.
