Initiation and growth behavior of very-long microstructurally short fatigue cracks
(Gruppo Italiano Frattura, 2013)
The present paper describes a novel experimental technique recently presented that allows one to study interactions between the crack and microstructural barriers with an unprecedented level of ease and detail. The method ...

Biaxial fatigue tests of notched specimens for AISI 304L stainless steel
(Gruppo Italiano Frattura (IGF), 2016)
High cycle fatigue tests were conducted for stainless steel AISI 304L. The geometry was a thin walled tube with a passing through hole. The tests were axial, torsional and in-phase axial-torsional, all of them under load ...

Variations on a critical distance theme
(Elsevier, 2021-11)
We investigate how the fatigue limit of notched specimens calculated with the Theory of Critical Distance (TCD) changes when variations in the value of the critical distance itself are considered. We motivate our study ...

An iterative technique to assess the fatigue strength of notched components
(Elsevier B.V., 2020)
The present work provides an efficient formulation to assess the growth of short fatigue cracks in metallic components. The proposed technique consists on the iterative combination of a micromechanical short-crack growth ...

Calculations of biaxial fatigue limits with models using the experimental crack direction
(Elsevier, 2023)
Several models from the literature were used to predict the fatigue limit in notched components subjected to biaxial cyclic loading. The predictions of these models are based on the elastic stresses along a line which is ...

Calculation of fatigue limits in notches with a micro-mechanical model in a simple way
(Elsevier, 2020)
Many methods have been proposed to predict fatigue failure in the presence of notches, among which is the N-R model. The N-R model is based on short-crack fracture mechanics. Specifically, the model analyses the capacity ...

Crack paths for mild steel specimens with circular holes in high cycle fatigue
(Elsevier B.V., 2022)
The most common current models for predicting the fatigue limit in notched solids use the stresses along a straight line, beginning at the notch root, to make the prediction. This line represents a simplification of the ...
