Аннотация
The technologies and results of an experimental determination of residual stresses in the impeller blades of a hydraulic unit of the Krasnoyarsk hydroelectric power plant obtained through technical diagnostics beyond the projected periods of use are presented. The investigations of the residual stresses were performed by strain measurement with excision of templates and the optical method of speckle interferometry. Factual values of the components of the residual stresses in two zones of the blade with nonuniform stress fields were obtained.
