Gradient elasticity: a transformative stress analysis tool to design notched components against uniaxial/multiaxial high-cycle fatigue [PDF]

, 2016
This paper investigates the accuracy of gradient elasticity in estimating high-cycle fatigue strength of notched components subjected to both uniaxial and multiaxial fatigue loading. A novel design methodology is formulated by combining Ru and Aifantis’

Crack path for run-out specimens in fatigue tests: is it belonging to high- or very-high-cycle fatigue regime? [PDF]

Fracture and Structural Integrity, 2015
Fatigue tests run-out specimens up to 106 – 5x107 load cycles are used to determine the stress level named “fatigue limit”. Nevertheless, it is not clear what kind of fatigue cracking takes or will take place in these specimens. To discuss this problem,

Assessment of Fatigue Life and Failure Criteria in Ultrasonic Testing Through Thermal Analyses

Applied Sciences
An experimental study was conducted to analyze temperature evolution during very high cycle fatigue tests. The temperature–number of cycles (T–N) curve is typically divided into three phases: Phase I—a rapid temperature increases at the start of the test,
