The objects of investigation are current and residual thermomechanical and microstructural states and cylindrical part's durability under multilayered surfacing and following thermal and mechanical cyclic loading. An aim of the work is to develop the continuum model and the numerical procedure of research of thermomechanical processes of multilayered surfacing of innelastic cylindrical bodies, estimation of their durability under following thermomechanical loading. The method of investigation is mathematical and numerical modeling of cylindrical body's multilayered surfacing on the basis of thermomechanics physically nonnlinear innelastic materials with microstructural transformations. A new mathematical model of multilayered surfacing of cylindrical bodies on the basis of the concept of self temperature-deformation state, which allows to determine the current and residual SSS and durability of cylindrical parts and to evaluate their durability under following thermomechanical loading. Numerical technique for implementing this model was developed. The results can be used to engineer new technologies of multilayered surfacing to forecast fatigue life and resource of surfaced cylindrical members.
