The effect of V-notch on the propagation rate of a fatigue crack
Hutař V., Knésl Z.
pages 110 - +8p, full text

The rate of a fatigue crack propagating in a vicinity of a V-notch is studied. To assess the influence of the constraint on the rate of the propagation, two parameter constraint based linear elastic fracture mechanics is used. The corresponding values of the T-stress are calculated and values of the effective stress intensity factor K'ff controlling the rate of a crack propagation are estimated as a function of the V-notch opening angle. The results obtained are compared with those for a crack emanatingfrom nonsingular U- notch concentrator.
