INVESTIGATION OF WAVE PROCESSES IN A THERMOELASTIC MICROPOLAR SOLID BODY BY THE METHOD OF THE THEORY OF CHARACTERISTICS
M. D. Martynenkoa and S. M. Bosyakovb UDC 539.3 Consideration is given to an elastic medium with a finite time of relaxation of the heat flux; the equations of motion of the medium are written in components of the tensors of force and couple stresses. Using the general theory of characteristics the explicit formulas for determination of the velocities of propagation of the discontinuity surfaces are obtained and the equations of the characteristic surfaces are derived. aBelarusian State University, Minsk, Belarus; bBrest State Technical University, Brest, Belarus.
