- Title
Paradoxical properties of nonstationary wavefields of point sources in isotropic elastic medium.
- Authors
Kiselev, A.; Tagirdzhanov, A.
- Abstract
Components of the nonstationary Green tensor for a homogeneous, isotropic, elastic medium, which are solutions of concentrated point force problems, are considered. As is known, they may include anomalous wavefield, which is nonzero between the wave front sets of the P and S waves and grows, in general, with time. In the paper, the time dependencies of the source for which the anomalous wavefield does not arise, are characterized.
