Abstract
Structural scheme of calculation procedure for estimation of stress-strain and microstructural state of parts during surfacing process and further operation is presented. The procedure is based on the following mathematical models: initial condition, including stress-strain and structural state in process of production surfacing; evolution of service and structural parameters in process of operation; accumulation of damageability and reduction of fatigue life; reconstruction surfacing. In comparison with experimental methods, mathematical modelling allows evaluating stress-strain and structural state of the parts in process of surfacing and further operation with lower expenses and more efficient. 20 Ref., 3 Figures.
