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 ...

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.

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.

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 ...

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.

Critical plane approach to multiaxial variable amplitude fatigue loading [PDF]
Fracture and Structural Integrity, 2015 A new critical plane approach based on the modified Manson-Coffin curve method (MMCCM) is presented in this paper for predicting fatigue lifetime under variable amplitude (VA) multiaxial fatigue loading.

Fatigue crack growth behavior under multiaxial variable amplitude loading [PDF]
Fracture and Structural Integrity, 2016 This study compares both uniaxial and multiaxial variable amplitude experimental crack growth data for naturally initiated fatigue cracks in tubular specimens of 2024-T3 aluminum alloy to predictions based on two state-of-the-art analysis codes ...

Crack propagation under variable amplitude loading [PDF]
Materials Research, 2013 Experience shows that a damage induced by a given cycle is dependent on the loading history. In this regard, the objective of this paper is to study and describe the phenomenology of the loading history on crack propagation.

SINUSOIDAL SIGNAL PARAMETERS IDENTIFICATION WITH UNKNOWN VARIABLE AMPLITUDE [PDF]
Научно-технический вестник информационных технологий, механики и оптики, 2018 The paper considers the problem of the frequency identification for a biased sinusoidal signal in the absence of measurement noise. It is assumed that the displacement and amplitude of the sinusoidal signal are unknown functions of time.
