A procedure was developed for modeling Gaussian wave pulse propagation in anisotropic solids and was tested on a fiber epoxy composite. Gaussian envelope broadening relative to the wave propagation velocity vector is discussed and the possible skewing effects resulting from this are assessed. Spreading rates and their dependence on pulse propagation direction are evaluated. More general initial profiles were attained by modeling the pulse as a Gauss-Hermite wave packet. It is shown that Gaussian wave packet transmission and reflection at curved interfaces can be solved. Computer-generated graphs depicting pulse orientation at various incidence angles are included.
