Original abstract

A numerical analysis by means of the ANSYS code revealed that the ratio of maximum values of mode III and mode II stress intensity factors reached the value of 1.37 . On the other hand, the ratio of crack tip opening displacements in the elastic-plastic range approaches the value of 2.7. These results can be used for the construction of fatigue crack growth rate curves in steels.

Czech abstract

Numerická analýza pomocí programu ANSYS ukázala, že poměr maximálních hodnot faktoru intenzity napětí v módech II a III je roven 1,37. Poměr otevření čela trhliny v elastoplastickém režimu se blíží hodnotě 2,7. Tyto výsledky mohou být využity k popisu rychlosti šíření smykových únavových trhlin v ocelích.
