SELF-ORTHOGONAL SEXTIC FORMALISM FOR ANISOTROPIC ELASTIC MEDIA - SPACES OF SIMPLE REFLECTION AND 2-COMPONENT SURFACE-WAVES

There are six polarization and traction vectors involved as normalized Stroh eigenvectors components in the subsonic surface wave theory. By introducing new sets of self-orthogonal vectors related to the Stroh eigenvector components, a series of linear dependence/independence rel ations between those vectors can be established. Using such a self-ort hogonal sextic formalism, analysis of the spaces of simple reflection, the existence of two component surface waves and supersonic surface w aves become more explicit and straightforward.
