Transient displacement fields in hexagonal crystals and transversally isotropic media

  • V. S. Budaev


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 [1] 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.
