Very high cycle fatigue of fiber‐reinforced polymer composites: Uniaxial ultrasonic fatigue
Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 9, Page 3083-3115, September 2024.Abstract This review explores uniaxial ultrasonic fatigue (USF) testing as a common and dependable method for quantifying the extended fatigue life of fiber‐reinforced polymer (FRP) composites. The objective is to explain the complexities governing the fatigue life behavior of FRPs, particularly in the realm of very high cycle fatigue (VHCF) where the ...

Procedia Structural Integrity, 2019 Abstract High-loaded tempered steels, being used in mobility, power generation and plant engineering, are frequently exposed to very high numbers of loading cycles (up to 1 billion cycles). Optimization and fatigue testing for such conditions is challenging and difficult, since damage is concentrated to very small areas of local cyclic plasticity ...
