Wave propagation in elastic media with stress‐induced anisotropy

Abstract

Summary. The effect of initial stress on the velocities of plane elastic waves is considered and corrections to the first order in terms of initial stress for P‐and S‐waves are obtained. The results are compared with those of Dahlen, who found that to the first order the initial stress had no effect on P‐wave velocities: this conclusion is shown to be correct only when the unstressed material is isotropic.
