摘要：
The propagation of three-dimensional plane waves at a traction free boundary of a half-space composed of triclinic crystalline material is discussed.A method has been developed to find the analytical expressions of all the three phase velocities of quasi-P (qP),quasi-SV(qSV)and quasi-SH(qSH)in three dimensions.Closed form expressions in three dimensions for the amplitude ratios of reflection coefficients of qP,qSV and qSH waves in a triclinic medium are obtained.These expressions are used for numerically studying the variation of the reflection coefficients with the angle of incidence.The graphs are drawn for different polar angle and azimuth.Numerical results presented indicate that the anisotropy affect the reflection coefficients significantly in the three dimensional case compared to the two-dimensional case.
