• ANTIPLANE SHEAR-WAVES

By the means of the guided wave theory, the scattering of SH guided wave by a circular inclusion in an infinite piezoelectric material strip is investigated. With the aid of repeated image superposition, the analytical expression of scattering wave is conducted, which satisfies the stress free and electric insulation conditions on the upper and lower horizontal boundaries of the strip. According to the boundary condition, integral equation is set up and analytical expression of dynamic stress concentration factor and electric field intensity concentration factor are obtained. The influence of the order of guided waves, the physical parameters of the medium and position of the circular inclusion on the dynamic stress concentration factor and electric field intensity concentration factor are analyzed and compared with the existing literature in calculating example.
