Gigacycle fatigue in high strength steels [PDF]
Science and Technology of Advanced Materials, 2019 This paper reviews the research results to date on gigacycle fatigue caused by internal fractures in high strength steels. Firstly, accelerated fatigue testing was realized using ultrasonic fatigue testing at 20 kHz, which completes 109 cycles in one day,

Comparison between dog-bone and Gaussian specimens for size effect evaluation in gigacycle fatigue [PDF]
Fracture and Structural Integrity, 2013 Gigacycle fatigue properties of materials are strongly affected by the specimen risk volume (volume of material subjected to a stress amplitude larger than the 90% of the maximum stress). Gigacycle fatigue tests, performed with ultrasonic fatigue testing

Multiscale study of fracture in aluminum-magnesium alloy under fatigue and dynamic loading [PDF]
Fracture and Structural Integrity, 2015 In this paper we investigated the influence of consecutive dynamic and gigacycle fatigue loads on the lifetime of aluminum-magnesium alloy AlMg6. Preloading of samples was achieved during dynamic tensile tests in the split-Hopkinson bar device.
