Dynamic Anti-plane Behavior of Piezoelectric Medium with a Cylindrical Inclusion in Right-angle Field

Abstract

Based on the complex variables and the mirror imaging methods, the dynamic anti-plane behavior of right-angle piezoelectric medium with a single cylindrical inclusion is studied. The analytical expressions of dynamic stress concentration factor (DSCF) and electric field intensity concentration factor (EFICF) at the inclusion in right-angle piezoelectric medium under the scattering of anti-plane shear waves are obtained, and the calculation results under different parameter combinations are plotted. The results indicate that the DSCFs and EFICFs around the inclusion is closely related to the frequency of incident wave, physical parameters of material and geometric parameters of structure.
