Abstract
The scattering problem of the SH wave on a limited permeable crack in a functionally graded piezoelectric substrate bonded to a homogeneous piezoelectric strip is investigated We adopted the limited permeable crack surface boundary condition By using the Fourier cosine transform this mixed boundary value problem is reduced to two pairs of dual integral equations which are solved numerically by the Copson method Numerical results showed the effects of gradient parameter electric loading electric boundary conditions incident angle thickness of PM strip the distance from the crack to the interface and wave number on the dynamic stress intensity factor
