The highest fatigue strength in terms of maximal load and number of cycles performed prior to failure was observed for the ContourLock group followed by the iBalance implants, the TomoFix standard (std) and small stature (sm) plates.
The PEEKPower group showed the lowest fatigue strength.
Meanwhile, it is also a negative factor for fatigue strength.
Fatigue strength σ f can be considered as failure strength s for a flywheel.
The fatigue specimens in air condition exhibited higher fatigue strength than those in corrosive condition, especially at low stress.
Under cyclic fatigue loading, the factors for the strengthening design of corroded RC beams fall in the order of stiffness, fatigue life, fatigue strength, and ultimate capacity.
Finally, fatigue strength master curve is constructed.
He's test beams were used to study the effect of the steel corrosion degree, the fatigue load range, and the prestress level on the fatigue life, fatigue strength, stiffness, and post-fatigue ultimate capacity.
The fatigue class (FAT) which was identified by the characteristic fatigue strength of the detail at two million cycles (Hobbacher 2003) for fatigue in air was 2 kN, whereas corrosion fatigue samples at this load fail at about 1,000,000 cycles.
(2) The Contour Lock plate provided highest fatigue strength followed by the size 2 Activmotion plate.
