Fatigue is one of the main causes of failures as well as mechanical fractures in structural details made of aluminium alloys under cyclic loading, where the materials (during the crack growth process) are subject to the ...

This work provides a numerical and experimental investigation of fatigue crack growth behavior in steel weldments including crack closure effects and their coupled interaction with weld strength mismatch. A central ...

The fatigue crack growth behavior of an austenitic metastable stainless steel AISI 301LN in the Paris region is investigated in this work. The fatigue crack growth rate curves are evaluated in terms of different parameters ...

In variable-amplitude loading there are interaction effects between the loading history and the crack propagation rate. The most important of these effects is the retardation in the crack propagation, which may raise the ...

© 2018 The Authors.Understanding how cracks behave in high toughness structural materials is critical for high responsibility applications. Design and fitness-for-service activities in this scenario are highly dependent ...

The usual approaches for Fatigue Crack Growth (FCG) assessment are based on semiempirical models that consider the stress intensity factor range of fracture mechanics, ΔK, as the governing driving force for crack propagation. ...
