Time-domain dynamic surface response of an anisotropic elastic solid to an impulsive line force

摘要

It is shown that the surface displacement response of a general anisotropic halfspace subjected to an impulsive line load can be obtained by purely algebraic means using a functional equivalence that exists between the time-space and Fourier domain dynamic Green's functions. Illustrative numerical results are presented for the silicon (111) surface that portray the role of bulk waves, surface waves (SAW) and pseudo-SAW.
