T. Boukharouba et al., THE USE OF NOTCH STRESS INTENSITY FACTOR AS A FATIGUE-CRACK INITIATION PARAMETER, Engineering fracture mechanics, 52(3), 1995, pp. 503-512
In the present paper the fatigue crack initiation is studied for welde
d joints and notched CT specimens made of mild steels. The experimenta
l results are analysed by the notch stress intensity factor K-p, psi c
riterion which depends on the notch angle psi acid on the acuity p. Th
is criterion allows a conservative design of structures.
