...: initiation and propagation phase. Despite 150 years of fatigue phenomenon research, there are still no clear solutions to this problem. Fatigue approaches, based on the fracture mechanics principles, are supported by fatigue crack growth models which are used to predict the crack propagation from an initial...

...Professor George Sih and Professor Konstantinos Tserpes; George Sih Purpose – Fatigue crack growth rate data for 2024-T3 aluminum are found using three parameters d*, σ* and μ* for short and long cracks for Regions I-III in conventional fatigue. Asymptotic solution...

... that the real fracture toughness of the material is lower than the calculated K_mat is 95 per cent, meaning a 5 per cent of confidence level; and P_f=0.5 is a medium probability (Figure 4). Structural integrity assessment Fatigue crack growth...

... stresses can also be used as tool to retard fatigue crack growth (FCG). In the presented paper, the use of a defocused laser to modify the residual stress state, and by that to retard the FCG, is examined. The focus lies on the simulation-based optimisation of the heating line position for achieving...
