Abstract: 
In the present paper, the residual strength of a pin-loaded lug and a finite plate, both with a semi-elliptical crack emanating from a hole, is examined. A new analytical methodology, based on Fracture Mechanics concepts, is proposed to analyse the crack propagation process in terms of life estimation and crack front evolution. Firstly, the stress field and the stress intensity factor are computed...
