Abstract
This paper presents two applications of a coupled finite element and boundary element method (FEBEM) to two-dimensional, transient problems of scattering of elastic SH waves. One application concerns multi-scattering: examples are shown for scattering from two semi-cylindrical inclusions embedded in a half-plane and separated by a small distance. Responses of one inclusion in the time and frequency domains are compared with those associated with a single inclusion. The other application concerns the effect of the size of the finite element mesh and boundary on accuracy. Response of the flat foundation with rectangular shape and seated on a half-plane is analyzed. It is shown that while simple silent boundaries are quite effective for large models, Rayleigh damping cannot model radiation damping effectively.
