Abstract
This paper analyses the influence of the discretisation of the crack front on the fatigue propagation prediction of semi-elliptical surface cracks. A simple method based on closed-form solutions for the stress intensity factor is used to discuss the effect of the discretisation. It is concluded that the analysis based on just two points along the crack front is sufficient to predict crack shape and fatigue life.
