The dual role of martensitic transformation in fatigue crack growth. [PDF]
Proc Natl Acad Sci U S A, 2022 Significance About 90% of all mechanical service failures are caused by fatigue. Avoiding fatigue failure requires addressing the wide knowledge gap regarding the micromechanical processes governing damage under cyclic loading, which may be fundamentally

Modelling fatigue crack growth in Shape Memory Alloys [PDF]
Fatigue & Fracture of Engineering Materials & Structures, 2021 We present a phase field-based framework for modelling fatigue damage in Shape Memory Alloys (SMAs). The model combines, for the first time: (i) a generalized phase field description of fracture, incorporating multiple phase field formulations, (ii) a ...

Cohesive zone modelling of hydrogen assisted fatigue crack growth: the role of trapping [PDF]
International Journal of Fatigue, 2022 We investigate the influence of microstructural traps in hydrogen-assisted fatigue crack growth. To this end, a new formulation combining multi-trap stress-assisted diffusion, mechanism-based strain gradient plasticity and a hydrogen- and fatigue ...

Effect of low temperature on fatigue and crack propagation behavior of aeronautic aluminium alloy
Journal of Aeronautical Materials, 2021 Fatigue and crack growth tests were performed on two categories of the common aeronautic aluminum- alloys 2524-T3 and 7050-T7451 at ambient temperature of 25 ℃ and cryogenic temperature of –70 ℃, in order to investigate the fatigue and crack propagation ...
