Equations describing the propagation of nonlinear quasitransverse waves in a weakly non-isotropic elastic body
Approximate equations are obtained, describing the propagation of a nonlinear quasitransverse wave of low amplitude, or a group of such waves, in a nearly isotropic elastic medium, when the characteristic velocities of the waves (dependent on their polarization) differ from one another by a small quantity.
