Laws of redistribution of residual stresses in a superficial layer of details at cation of cyclic loadings

摘要

The mathematical model of redistribution of residual stresses in a superficial layer hardenings out-striping superficial plastic deformation of details based on the decision of a task of the theory of plasticity in view of the abnormal mechanical characteristics of a superficial layer and features cyclic loading of details by amplitudes, appropriate to a limit of endurance is offered. The opportunity of forecasting of a limit of endurance limits of hardenings details is reasonable on the basis of the developed model, the theoretical results of the forecast with experimental confirmation are submitted.
