Název v původním jazyce

Crack propagation under nonzero mean combined loading

Popis výsledku v původním jazyce

Proposed scientific research brings new knowledge about crack propagation during tests which were performed. These tests were unique by combination of normal and shear mean stresses. The mean values in normal and shear components were proposed in the ratio 3:2 in agreement with the coefficient kc which corresponds with ratio of fatigue limits in tension and torsion. Except for static pre-stresses in both stress components, the conception includes one dynamical normal component with sinusoidal 10 Hz loading. The specimens were tubular with 30 mm diameter, wall thickness 2 mm and a notch in the shape of one-sided transverse hole of diameter 3 mm positioned in the middle of the specimen. The specimens were made of structural low carbon steel ČSN 41 1523.1after normalization annealing. The experiments were carried out on an electrohydraulic computer-controlled testing machine Inova ZUZ 200-1.
