Dynamic interaction of anti-plane shear waves with arc-shaped interfacial crack in piezoelectric media.
The dynamic interaction between anti-plane shear waves with arc-shaped interfacial crack of piezoelectric media is considered here. The region of the debonding is modeled as an arc-shaped interfacial crack with non-contacting faces. The electric permeable and impermeable boundary conditions are adopted to get the disturbed solution, respectively. The crack opening displacement and the electric potential are represented by Chebyshev polynomials and a system of equations is derived. The calculation results show that the piezoelectric coefficient has remarkable effect on the crack opening displacement.
