On a point source of harmonic oscillations in a homogeneous anisotropic elastic medium

A point source of harmonic oscillations in an infinite homogeneous anisotropic elastic space is considered. It is shown that everywhere, except for certain directions, the phase function of the problem solution can be determined by applying the Legendre transform to the characteristic function of the equations. The group velocity of the solution is directed from the point source precisely along the radius. Bibl. 2 titles.
