UDC 539.3

The equations of motion of a two-dimensional cubically 
anisotropic thermoelastic medium in stress-tensor components have 
been obtained. The equation of characteristics has been derived and 
the dependences of the phase and group velocities of propagation of 
discontinuity surfaces on the slope of the normal to the characteristic 
surface and the period of relaxation of the heat flux have been investigated 
using this equation.
