The influence of crack tip shielding on fatigue crack propagation [PDF]
Fracture and Structural Integrity, 2017 The fatigue crack propagation is one of the major problems and of the real concern in the evaluation of the structural integrity of components. This is due to the fact that once a fatigue crack has been detected it is also known its effect on the ...

Effects of residual stresses on fatigue crack propagation of an orthotropic steel bridge deck
Materials & Design (1980-2015), 2021 Orthotropic steel decks (OSD's) are susceptible to fatigue failure due to cyclic loading. Often fatigue cracks are found in the joint between the deck plate and the trough. Due to the welding process, residual stresses are present in and around the joint.
