Use of mathematical modeling of the mechanics of residual stresses for forecasting a limit of endurance of endurance of details on formation of a crack

摘要

Use of mathematical models of formation and redistribution of residual stresses is offered at cyclic deformation for forecasting a limit of endurance of details on formation of a crack. The results of modeling of the residual stress-deformed conditionприповерхностного of a layer, results of accounts of criterion of influence of residual stresses and dependence of his size with sizes of amplitude of external loading are given. The theoretical results of the forecast with experimental acknowledgement are submitted.
