THERMOELASTIC MATERIALS

A characteristic equation for a system of equations of 
motion of a cubically anisotropic medium with allowance for the relaxation 
time of thermal disturbances has been obtained, and expressions for 
the velocities of propagation of modified elastic and thermal waves 
have been found. The surfaces of inverse velocities have been constructed 
and the influence of the effect of interrelationship of thermal and 
mechanical fields on the change in the phase velocities of propagation 
of a quasilongitudinal elastic wave and a thermal wave in different 
planes of a cubically anisotropic material has been analyzed.
