The authors present an approximate statement of axisymmetric dynamical problem of thermoviscoplasticity with allowance for the connectedness of the mechanical and thermal fields. In the statement an approximate cyclic model of thermoviscoplasticity is used, which is based on the concept of complex moduli. Main regularities of distribution of the field values and the temperature and amplitude frequency resonant characteristics of a circular disk are studied in the case of forced axisymmetric bendin g oscillations.
