Bending Fatigue Behavior of 7075-Aluminum Alloy
Key Engineering Materials, 2018Light alloys are a very interesting challenge in order to have light components with high mechanical features. One of these is the 7075 aluminum alloy, which is commonly employed in aeronautic, automotive and maritime fields.On the other hand, the application of a PVD (Physical Vapor Deposition) coating can improve the hardness of the surface and the ...

Bending fatigue and contact fatigue characteristics of carburized gears
Surface and Coatings Technology, 1995Abstract In order to assure reliability, the manufacture of gears for power transmission in high load bearing applications requires precise control of a wide range of processing parameters during manufacture, aimed at achieving specific material properties. Process selection and control in forming and heat treatment operations plays a crucial role in

Estimating PM Gear Fatigue Strength From Bending Fatigue Data
World PM2022 Proceedings, 2022Gears are an interesting application for pressed and sintered applications, and having accurate fatigue data is often a pre-requisite for starting a new gear design. Ideally gear fatigue strength is tested on gears, but that is not always possible. At the same time standard bending fatigue data are often more readily available.

Conjoint bending torsion fatigue — fractography
Materials & Design, 2002Abstract The fractography of conjoint bending torsion fatigue (CBTF) has been reported in this paper for a superalloy (Nimonic 75A) material used in gas turbine engines. The fracture surface features were characteristic of bending fatigue (BF), a distinct area of CBTF, and a region between the BF and CBTF, overloading (OL). Striations were documented

Renal Artery Stent Bending Fatigue Analysis
Journal of Medical Devices, 2006During normal breathing, the kidneys move up and down due to the diaphragm motion and the renal artery subsequently experiences bending. Whether bending of the renal artery during respiration impacts stent bending fatigue was not previously known. This study presents the first evaluation of the effect of the kidney movement on renal stent bending ...

Bending fatigue of hybrid composite rods
Composites Part A: Applied Science and Manufacturing, 2011The flexural fatigue behavior of hybrid composite rods comprised of unidirectional carbon and glass fibers was investigated. Damage was evaluated by monitoring stiffness loss as a function of cycles, and bending fatigue failure was defined in terms of strength retention.
