ANALYSIS OF DYNAMIC ANTI-PLANE CHARACTERISTICS OF CIRCULAR INCLUSION AND SEMICIRCULAR DEPRESSION IN STRIP PIEZOELECTRIC MEDIA BY SH GUIDED WAVE
The guided wave theory is used to study the scattering of SH guided waves in circular inclusions and semi-circular depressions in infinite piezoelectric strips.The semi-circular depression at the boundary position is treated by the multi-pole coordinate variation method.Using the contingency image method,the theoretical expression of the scattered wave satisfying the stress-free and electrical insulation conditions at the upper and lower boundaries of the band is constructed.Based on the boundary conditions,an integral equation is established.An analytical expression for the dynamic stress concentration factor (DSCF) and electric field intensity concentration factor (EFICF) are obtained.The DSCF and EFICF are analyzed by analyzing the order of the guided wave and the physical parameters of the medium,and compared with the existing literature in the calculation example.
