To study the way that the plane SH wave propagating in an elastic bi-material half space from medium Ⅰto medium Ⅱ,the steady-state scattering of the transmitted wave by a circular cavity is analyzed by using Green function and integral equation methods on complex function description.The bi-material half space is divided into a quarter space medium Ⅰ and a quarter space medium Ⅱwith a circular cavity in it.Their Green functions are constructed as anti-plane point source response problem respectively.The total displacement fields of medium Ⅰ and medium Ⅱ are formulated as two parts'vector sum.The first part is interfacial integral of interactive force multiplied by corresponding Green function.The second part is plane displacement field formed by omitting the circular cavity.Steady state solution is obtained by determining the integral equations along interface with displacement continuity.Numerical results are presented to reveal the effects of locations and material parameters on circular cavity scattering.
