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,

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
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
The stability of weak quasi-transverse shock waves in a weakly anisotropic elastic medium with respect to arbitrarily oriented perturbations is investigated in the linear approximation. It is shown that fast quasi-transverse shock waves are stable.
