研究了无限远平面压缩波作用下含圆孔功能梯度材料（FGM）板的二维动应力。采用分段均匀分层法，基于复变函数法推导了径向任意材料参数的功能梯度板的动应力分布。作为算例，给出了给定径向剪切模量、密度和泊松比的FGM板的数值结果。结果表明，在不同频率的入射波作用下，通过选择合适的径向材料参数变化方式，可以有效地降低FGM板圆孔周围的动应力。
This paper is to study the two-dimensional dynamic stress of a functionally graded material (FGM) plate with a circular hole under plane compressional waves at infinity. With using the method of piece-wise homogeneous layers, the dynamic stress distribution of the FGM plate having radial arbitrary material parameters is derived based on the complex variable method. As examples, numerical results are presented for the FGM plate having given radial shear modulus, density and Poisson’s ratio. It is found that the dynamic stress around the circular hole in the FGM plate can be effectively reduced by choosing the proper change ways of the radial material parameters for different frequency incident wave.
