Very high cycle fatigue of fiber‐reinforced polymer composites: Uniaxial ultrasonic fatigue
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 ...

Novel technique of vibration minimization during hard machining
This research study examines the performance of electrorheological fluids, also referred to as smart fluids, which have gained popularity because they instantly alter when exposed to an external magnetic or electric field. When high voltage is applied, the ER fluid quickly changes from a viscous liquid to a semisolid state, which is reversible.
