Popis: Presented are results of photoelastic study on the stress-strain state of some critical parts and components of hydropower equipment such as the distributor (manifold) of a Pelten turbine, threaded studs for large pressure vessels and turbine cover, welded joint between blades and the rim of a Francis turbine weakened by cracks. Stress-intensity factors depending on the shape, position, size, and the interaction of cracks are obtained. Formulas based on the experimental results are proposed.
