“…Also, in-house developed software is an option to be considered, 80 where FCG rate of T3 and T351 tempered aerospace grade Al 2024 alloy was evaluated by using the XFEM, coupled with a genetic algorithm (GA) in the framework of an in-house developed MATLAB code. 80 The numerical simulation was performed using Paris, Forman, and NASGRO laws, the last one providing the highest FCG rate prediction. Similar approach was used in Živojinovi c et al, 81 where practical aspects of fail-safe design calculation of fatigue life of cracked thin-walled structures were analyzed, leading to the same conclusions about FCG rates.…”

Numerical simulation of fatigue crack growth (FCG) is presented, based on the application of the extended finite element method (XFEM). Couple of case studies are presented, as a review of recent experience of the Belgrade school of XFEM simulations, established at the Faculty of Mechanical Engineering. Case studies comprised Charpy specimen with initial crack at the notch tip, oil rig pipe with an axial surface crack, pressure vessels with a crack at the welded joint with connecting pipe, turbine shaft with a crack at the transition radius, optimization of a wing spar in respect to FCG, the effect of mesh size on fatigue life estimation of a stringer panel, fatigue life estimation of wing‐to‐fuselage connecting lug, geometry effect on fatigue life of orthopedic plates and fatigue life of hip implant. Based on these case studies, XFEM is discussed in respect to its accuracy and efficiency. It is concluded that XFEM is a versatile tool for simulation of FCG, providing an excellent option for precise and reliable fatigue life of a cracked component.
