“…The stress intensity factors were however obtained via the J-contour integral. A similar two-dimensional study of pin-loaded attachment lugs with single edge cracks at the pin-hole has also been recently carried out by the present authors [16], but using the approach developed in [14].…”

In this paper, a formulation based on the iterative-load incremental approach for the three-dimensional frictional contact mechanics analysis of fracture problems using the boundary element method (BEM), is presented. Special crack front elements are employed to provide a quick and direct means of obtaining the stress intensity factor. The veracity of the formulation is demonstrated with four crack problems. Three of these problems involve crack closure under bending loads, and the fourth is that of a pin-loaded rectangular plate with comer cracks at the pin-hole. The computed BEM solutions are compared, where possible, with those available in the literature, and there is generally good agreement between them. The numerical examples serve also to illustrate the need for a proper contact mechanics treatment to obtain accurate stress intensity factors for such problems.

“…The nonlinear behaviour of the fastener hole with through‐the‐thickness crack has numerically been analysed by Mahendra Babu et al applying the finite element method. For the fatigue assessment of the same crack configuration located at the pin‐loaded hole, Liu and Tan have employed the boundary element method whereas Narayana et al have used the finite element method and a modified crack closure integral technique. According to Antoni and Gaisne and Guo, analytical concepts have been applied to analyse the behaviour of through‐the‐thickness and quarter‐elliptical corner crack configurations, respectively.…”

In the present paper, computational framework for fatigue performance analysis of a semicircular edge notch with a through‐the‐thickness crack or a semielliptical crack is discussed. The failure behaviour of such configurations is theoretically examined through the stress‐intensity analysis and residual life estimation. The stress field of a damaged notch configuration is herein investigated by employing analytical and numerical approaches. Further, a fracture mechanics–based methodology, developed for fatigue life assessment, is taking into account the crack growth model proposed by Huang and Moan in which the stress ratio is involved. The efficiency of the obtained fatigue damage assessments, related to the edge notch configurations, is verified through appropriate experimental observations.
