Abstract EN
This paper presents a modified boundary element method (BEM) to solve the scattering problem of Love surface wave from a two-dimensional cavity defect.
Because of the truncation of BEM models at a far distance from the cavity, spurious reflected waves are generated.
In order to eliminate the unwanted reflections, the guided Love-wave displacement patterns are assumed on the far-field infinite boundaries previously omitted by model truncation, and they are incorporated into the BEM equation set as modified items.
The numerical results are verified by theoretical solutions of far-field Green’s functions.
Additional parametric studies are performed to find out the influence of truncation distance and defects’ geometric characters on the accuracy of scattered wave solutions.
