Fatigue crack initiation occurs at the surface, although sub surface nucleation has also been reported. Localized imperfections like inclusions close to surface and surface small pits can result in crack sources. Coatings ...

In this study, a model of fatigue life estimative based on dynamic mechanical analysis and fatigue tests is validated. Storage modulus is the viscoelastic parameter which better correlate with fatigue resistance. Accordingly, ...

AA7050-T7451 aluminum alloy is one of the most used material in aeronautical applications due to its high strength/density ratio and good fatigue resistance. More recently the AA2050-T84 alloy was introduced due to its ...

This paper deals with the prediction of high-cycle fatigue behaviour for four different materials (a 7075-T6 alloy, a Ti-6Al-4V alloy, JIS S10C steel and a 0.4%C steel) using Chapetti´s approach to estimate the fatigue-crack ...

Shot peening is a method widely used to improve the fatigue strength of materials. through the creation of a compressive residual stress field (CRSF) in their surface layers. In the present research the gain in fatigue ...

Low-cycle fatigue life of Grade 300E and 500E reinforcing bars including the effect of buckling is evaluated. Low-cycle fatigue tests are carried out on un-machined specimens subjected to constant axial strain loading with ...
