| Abstract: | FEM cloning method is introduced to deal with the problem of scattering of elastic waves, and is validated by the scattering fields around a cylindrical discontinuities. It can take into account the Sommerfeld's radiation condition, can be used to the cases of excavated and flexible base with irregular bounds, and has all of the advantages of FEM, thus it may be applied to the earthquake engineering problems easily. |
