Study of stress concentration in some critical parts of hydraulic machines

The paper considers results of experimental study of stress concentration in the blade guide vane of reversible hydraulic machines and blades of Kaplan turbines. The values of stress concentration factors and stress distribution in typical cross sections of parts have been obtained. Approximate analytical methods of calculation being in good agreement with experimental data have been proposed. The recommendations for improving the design have been given.

Stress state of band with the system of periodic cracks

The results of experimental study of stress concentration around the tip of transverse cracks in crossband have been considered. The study has been carried out by the method of photoelasticity using "freezing" of deformations. The values of the stress intensity factor of the first and second types have been received. The experimental results are in good agreement with the theoretical solution.
