Notes:
Based on Green’s function, complex function and multi-polar coordinate system, the farfield solution of SH wave scattered by an elastic half space with a circular cavity and a crack at anarbitrary position and orientation is investigated. First, a suitable Green’s function is constructed,which is the fundamental solution of the displacement field for a half space with a circular cavitysubjected to an out-plane time-harmonic line force at an arbitrary position in half space. Second, bymeans of crack-division technique, a crack with any location and orientation can be constructed inthe region of the half space. The displacement field and stress field are established in the situationof coexistence of circular cavity and crack. At last expressions of far field, such as displacementmode of scattering wave are deduced. Some examples and numerical results are illustrated. Theinfluences of the combination of different media parameters on solutions of far field are discussed
