研究了无限大功能梯度圆板在点冲击载荷作用下的波传播和瞬态响应。假设有效材料性质随厚度坐标的幂形式变化。考虑横向剪切变形和转动惯量的影响，得到了板的控制方程和解析频散关系。利用频散关系和积分变换，得到了功能梯度板在点冲击载荷作用下的精确积分解。详细讨论了体积分数分布对功能梯度板波传播和瞬态响应的影响。
Wave propagation and transient response of an infinite functionally graded circular plate under a point impact load are studied. The effective material properties are assumed to vary as a power form of the thickness coordinate. Considering the effects of transverse shear deformation and rotary inertia, the governing equations and analytic dispersion relation of the plate are obtained. Using the dispersion relation and integral transforms, exact integral solutions of the functionally graded plate under a point impact load are obtained. The influence of volume fraction distributions on wave propagation and transient response of functionally graded plates is discussed in detail.
