A modified fatigue damage model considering loading sequence effect
International Journal of Damage Mechanics, 2022A modified fatigue damage model is proposed considering the loading sequence effect under variable amplitude loading conditions. The transition sequence is obtained from the counting sequence by an equivalent rainflow counting method and is used to provide the loading sequence information for fatigue damage accumulation prediction.

Load Sequence Effect on Fatigue Damage
Key Engineering Materials, 2011Reliable damage tolerant design of airframe structures relies on the accurate life prediction of fatigue cracks propagating from a detectable size to the critical size, which is challenging due to the complex load sequence effect under spectrum loading.

Notched fatigue behavior including load sequence effects under axial and torsional loadings
International Journal of Fatigue, 2013Abstract Notch effects on axial and torsion fatigue behaviors of low carbon steel were investigated. Fully-reversed tests were conducted on thin-walled tubular specimens with or without a transverse circular hole. A shear failure mechanism was observed for both smooth and notched specimens and under both axial and torsion loadings.

The effect of load sequence on GRMS measurements
Proceedings of the 1997 IEEE/ASME Joint Railroad Conference, 2002The Gage Restraint Measurement System (GRMS) is an instrumented railroad car which measures the effectiveness of the ties and fasteners in maintaining gage under load. This involves applying a gage-widening load and measuring the resultant change in gage.

The transfer of movement sequences: Effects of decreased and increased load
Quarterly Journal of Experimental Psychology, 2007A number of recent experiments have demonstrated that a movement structure develops during the course of learning a movement sequence that provides the basis for transfer. After learning a movement sequence participants have been shown to be able to effectively produce the sequence when movement demands require that the sequence be rescaled in ...

Effect of Fatigue Step Loading Sequence on Residual Strength
Tire Science and Technology, 2000Abstract Miner's rule is often assumed to hold in accelerated fatigue tests. This rule implies that the order in which loads are applied is not significant. Whether particular loads are applied early in the test or later is unimportant; they are expected to cause the same amount of damage if they are imposed for the same number of cycles.

Multiaxial fatigue of titanium including step loading and load path alteration and sequence effects
International Journal of Fatigue, 2010Abstract Load sequence effects on low cycle multiaxial fatigue behavior of titanium are investigated in this study. Constant and variable amplitude axial, torsion, as well as in-phase and out-of-phase axial–torsion strain-controlled tests were conducted on tubular specimens made from pure titanium and titanium alloy BT9.

Loading sequence effects on dragload and downdrag for pile foundation
Transactions of Tianjin University, 2010Negative skin friction (NSF) is one of the important problems when designing a pile foundation. However, the influence of loading sequence on the dragload and downdrag for pile foundation is seldom studied. In this paper, a three-dimensional numerical model was established using FLAC3D.

Load sequence effects and variable amplitude fatigue of superelastic NiTi
International Journal of Mechanical Sciences, 2018Abstract Fatigue behavior of superelastic NiTi alloys under variable amplitude loading is experimentally studied and two energy-based fatigue models were used to analyze the fatigue behavior. Cyclic tests were conducted in strain-controlled condition.

An Engineering Model for Assessing Load Sequencing Effects
1980An engineering model has been developed to assess the impact of load spectrum variables on fatigue crack growth in metal structures. The model is based on the effective stress concept of Willenborg et al and Gallagher et al, and has been extended to accommodate retardation/acceleration phenomena peculiar to transport spectra.
