METHOD OF CHARACTERISTICS FOR THE DYNAMIC THERMOELASTIC PROBLEM OF A CUBICALLY ANISOTROPIC BODY IN STRESSES
M. D. Martynenko and S. M. Bosyakov 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.
