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 second year a bimaterial problem is considered.application/pdf184602 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雙材料elastic wave propagationanisotropic materialburied sourcebimaterialreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/21739/1/932212E002027.pdf
