Transient displacement fields in hexagonal crystals and transversally isotropic media
The structure of the disturbed region and the geometry of the wave front is investigated under the condition that a concentrated source of the instantaneous-pulse type is acting in an unbounded transversally isotropic medium. The regions of permissible values of the anisotropy coefficient introduced in  for transversally isotropic media on the basis of conditions of the elastic energy's positive-definiteness and hyperbolicity conditions are determined. It is suggested that motion of the medium occurs under conditions of plane deformation.
