摘要: This paper is to study the two-dimensional dynamic stress of a functionally graded material (FGM) plate with circular hole under plane compressional waves at infinity. With using method piece-wise homogeneous layers, distribution FGM having radial arbitrary parameters derived based on complex variable method. As examples, numerical results are presented for given shear modulus, density and Poisson’s ratio. It found that around in can be effectively reduced by choosing proper change ways different frequency incident wave.
