Lelyukh Y. Resonance vibrations and dissipative heating of nonelastic ferromagnetic bodies of canonic forms.

The Thesis is devoted to the formulation and development of numeric-analytic methods of solution of conjugate magnetomechanical problems about forced vibrations and dissipative heating of viscoelastic ferromagnetic bodies with account of connecting magnetomechanics and thermal fields. For high-frequency vibrations of viscoelastic ferromagnetic layer the solutions were obtained where the interaction exchange, gyromagnetic effect are taken into account. In low-frequency area a solution of axisymmetrical problems of thermomagnetoviscoelasticity were obtained by the finite element method. The problem of resonance vibrations and dissipative heating of ferromagnetic hollow cylinder and spherical cap were solved. On this base the influence of different factors -- gyromagnetic effect and interaction exchange, the magnetic boundary conductions, the geometric configuration of bodies, external medium was investigated.
