| Abstract: | The performance of a coupled Finite Element—Analytic method in solving elastic wave scattering in infinite spaces is studied for plane SH-waves. The influence of several parameters on the accuracy of the results is investigated. These parameters are the number of terms in the series solution, the number of compatibility points across an imaginary circular interface (i.e. the points for which the continuity of both stresses and displacements are enforced), and the ratio of element dimension to wavelength in the direction of propagation. It was found that the method converges rapidly with the number of terms. Furthermore, both element dimension to wavelength ratio and the number of compatibility points significantly influence the accuracy of the approximate solution. |
