Influence of corrosion and creep on intergranular fatigue crack path in 2XXX aluminium alloys [PDF]

, 2010
In this paper, two examples of the influence of time-dependent processes on crack path in two 2XXX aluminium alloys are presented. The first example is concerned with corrosion–fatigue crack growth resistance of a 2024 T351 alloy cracked in the S–L ...

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Elastoplastic modeling of fatigue cracks

Omsk Scientific Bulletin
The presented work provides a detailed analysis of modern approaches to creating elastoplastic models of surface crack growth that take into account the influence of the type of biaxial loading on the development of stresses and strains at the crack tip and, accordingly, on the crack growth rate.

Using low-cycle fatigue method to predict fatigue life of rail crack initiation location by means of 3D-finite element simulation on sharped curved track [PDF]

International Journal of Railway Research, 2023
Dynamic modeling of wheel-rail interaction is significant for accurate fatigue analysis of railways. Both the location and magnitude of wheel-rail stress must be evaluated accurately and efficiently via computational tools.

Finite element analysis of the influence of a fatigue crack on magnetic properties of steel [PDF]

, 1998
Fatigue can affect the magnetic properties of materials due to microstructural changes. Previous investigations have shown that several structure sensitive magnetic properties, such as coercivityHc and remanenceBr, changed systematically as a result of ...
