Strain-measurement-based calculation and experimental determination of stresses on equipment internal surfaces.

The paper considers an algorithm used for stress-strain state (SSS) determination in an NPP pipeline junction with vessel components. The tensometry results obtained for cylindrical sections of the pipeline, distant from the areas of geometrical discontinuity and stress concentration locations, are used in this case. The temperature fields are taken from solutions of inverse thermoelasticity problems, which allow one to determine the temperature of the coolant and its coefficients of heat transfer to the structure surface.
