A new method proposed by Wu (2000) for anisotropic elastodynamics is extended to treat the problem. A major advantage of the method is that explicit solution can be derived without the use of integral transforms. Furthermore, individual reflected and refracted waves can be clearly identified in the solution. In the first year a halfspace is considered.application/pdf212006 bytesapplication/pdfzh-TW國立臺灣大學應用力學研究所彈性波傳異向性材料掩埋波源半空間elastic wave propagationanisotropic materialburied sourcehalf-spacereporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/21711/1/922212E002067.pdf
