| 摘 要： | This paper investigates the dynamic behavior of a buried rigid ellipticcylinder partially debonded from surrounding matrix under the action of anti-planeshear waves (SH waves). The debonding region is modeled as an elliptic arc-shapedinterface crack with non-contacting faces. By using the wave function (Mathieufunction) expansion method and introducing the dislocation density function as anunknown variable, the problem is reduced to a singular integral equation which issolved numerically to calculate the near and far fields of the problem. The resonanceof the structure and the effects of various parameters on the resonance are discussed. |

| Abstract: | This paper investigates the dynamic behavior of a buried rigid elliptic cylinder partially debonded from surrounding matrix under the action of anti-plane shear waves (SH waves). The debonding region is modeled as an elliptic arc-shaped interface crack with non-contacting faces. By using the wave function (Mathieu function) expansion method and introducing the dislocation density function as an unknown variable, the problem is reduced to a singular integral equation which is solved numerically to calculate the near and far fields of the problem. The resonance of the structure and the effects of various parameters on the resonance are discussed. |
