Mechanics issues related to the formation and growth of cracks ranging from subgrain
dimension to up to the order of one mm are considered under high cycle fatigue (HCF) …

In this study, fatigue crack initiation in pure α-iron is investigated through a microstructure-
sensitive framework. At first, synthetic microstructures are modeled based on an anisotropic …

Recent accidents involving railway rails have aroused demand for improved and more
efficient rail maintenance strategies to reduce the risk of unexpected rail fracture. Numerical …

Surface-breaking cracks occur in railheads due to unidirectional material flow caused by
ratchetting from repeated contact loading. This type of crack is frequently observed on the …

Rolling contact fatigue cracks in rails undergo non-proportional mixed-mode I+ II+ III, in
variable proportions along their front. In order to determine the crack growth thresholds and …

Fatigue crack growth tests in mixed-mode II+ III were performed on maraging steel and Ti-
6Al-4V. The 3D evolutions of the crack fronts-measured by SEM after interrupted tests-were …

This article provides information on the typical experimental observations of formation and
propagation of small fatigue cracks under various stress states and explores the relation to …

Numerous cases of damage by fatigue in structures are related to mechanical stresses due
to mixed mode loading conditions. To prevent such cases of failure a precise knowledge of …

The design of components against fatigue failure may involve several considerations of
irregular loading, variable temperature, and environment. This article focuses on design …
