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