The conditions for the sign of the deviation of ray from wave normal (sgn A) specified on p. 209 of [1 ] and the criteria for cusps to occur on the elastic wave surface given in [2] are valid provided that all principal extensional stiffnesses exceed principal shear stiffnesses, i.e., cjj(j = 1, 2,

The geometry relating to the tangent plane at a stationary point on a surface has been used to re-examine various criteria for the existence of parabolic points (inflexions in 2D-sections) on the outermost sheet of the slowness surface for elastic waves in anisotropic media. Previous results obtain
Two additional criteria for the existence of cusp points on elastic wave surfaces are developed. A previously published method [1] is extended to give a simple necessary and sufficient condition for cusps about (1, 1, 0) axes in cubic and tetragonal media. This criterion is plausibly adapted to pro
A modified transfer-matrix method is proposed to describe Love waves in multilayered anisotropic (monoclinic) media. Dispersion relations for media consisting of one and two anisotropic elastic layers in contact with an anisotropic half-space are obtained in closed form. The conditions for Love wave
