Scattering of SH-wave from the Two Collinear Cracks in Functionally Graded Piezoelectric Strip Which Is Bonded to the Infinite Piezoelectric Material

ZHOU Chunmei;School of Mathematics and Computer Science,Ningxia Normal University;  
This paper discuss the problem of SH-wave scattering from two collinear cracks in Functionally Graded Piezoelectric strip,which is bonded to the infinite Piezoelectric Material. Under the permeable boundary conditions,using the fourier transforms to reduce the problem to a pair of dual intergral equations,The integral equations are solved by using of the Copson method.In the end,the numerical examples show that the effects of the frequency of wave and material distribution on the intensity factor.
