Damage accumulation of bovine bone under variable amplitude loads [PDF]
Bone Reports, 2016 Stress fractures, a painful injury, are caused by excessive fatigue in bone. This study on damage accumulation in bone sought to determine if the Palmgren-Miner rule (PMR), a well-known linear damage accumulation hypothesis, is predictive of fatigue ...

Prediction of Fatigue Crack Initiation under Variable Amplitude Loading: Literature Review
Metals, 2023 Metallic materials are widely employed in engineering constructions, and one of the most common failure mechanisms in metals is fatigue failure. Even though metal fatigue has been studied for almost 160 years, many problems remain unsolved.

Deneb Is a Large-amplitude Polarimetric Variable
The Astrophysical Journal LettersWe write to report the discovery that Deneb is a large-amplitude polarization variable. Over a ∼400 days time span from 2022 August Deneb’s polarization was typically around 3900 parts per million (ppm) in the SDSS ${g}^{{\prime} }$ band.

Fatigue Life Estimation of Structures under Statistically and Spectrally Similar Variable Amplitude Loading [PDF]
, 2021 Engineering fatigue is a very prevalent and dangerous phenomenon that limits the useful life span of mechanical structures. It can be found in most engineered structures and machinery that are made from metallic or composite materials.

Very High Cycle Fatigue Damage of TC21 Titanium Alloy under High/Low Two-Step Stress Loading
Crystals, 2023 Very high cycle fatigue (VHCF) tests were carried out under variable amplitude loading for TC21 titanium alloy. The first level of high amplitude loading was set as 950 MPa close to yield strength, and the second level of low amplitude loading was ...

Mean Stress Effect in High-Frequency Mechanical Impact (HFMI)-Treated Steel Road Bridges
Buildings, 2022 High-frequency mechanical impact (HFMI) is a post-weld treatment method which substantially enhances the fatigue strength of steel weldments. As such, the method enables a more efficient design of bridges, where fatigue is often the governing limit state.

REINFORCING SACCADIC AMPLITUDE VARIABILITY [PDF]
Journal of the Experimental Analysis of Behavior, 2011 Saccadic endpoint variability is often viewed as the outcome of neural noise occurring during sensorimotor processing. However, part of this variability might result from operant learning. We tested this hypothesis by reinforcing dispersions of saccadic amplitude distributions, while maintaining constant their medians.

Quantitative thermographic method for fatigue life prediction under variable amplitude loading
Fatigue & Fracture of Engineering Materials & Structures, 2022 Quantitative thermographic methodology (QTM), which takes energy dissipation as a fatigue indicator, has been successfully applied to predict the fatigue life of materials and welded joints under constant amplitude loading.
