Dynamic analysis for a subsurface elastic cylindrical inclusion with a semi-cylindrical hill Under SH-wave
An analytic method is developed for scattering of SH-wave by a subsurface elastic cylindrical inclusion below a semi-cylindrical hill. During the solution, the whole model is divided into two parts. The first one is a circular domain which includes the boundary of the hill, and all the rest can be considered as the second one. Then the displacement solutions satisfying the boundary conditions are constructed in two parts respectively. According to the conjunction condition of junction interface, two domains are matched up on common boundary by the method of moving coordinate. Then employed to the boundary condition around the elastic cylindrical inclusion,a series of infinite algebraic equations about the problem can be obtained. The calculating results of dynamic stress concentration factor around elastic cylindrical inclusion are plotted to show the effect of some parameters on DSCF.
