METHOD FOR DETERMINATION OF RESIDUAL RESOURCE OF METAL ARTICLES

摘要

The invention relates to machine-building, power, aviation industries. Method for determination of residual resource of metal articles includes testing on tension of samples made of material, determination of physical-mechanical characteristics of samples of materials by method of non-destructive control with determination of step of loading according to given mode of loading of articles. According to the invention one determines average limiting deformations of material with formation of massif of structural elements of those, after known working-one, one determines real condition of material of article and change of average limiting deformations. One obtains fatigue diagrams for resulting structural state and state of material after working-on. Residual resource of determines from comparison of respective resources of articles in initial state and after loading. The invention provides increase of accuracy of determination of residual resource.
