Fatigue damage assessment of bogie frame based on an improved nonlinear cumulative damage model [PDF]

open access: yesScientific Reports
The structural damage of rail vehicle bogie frames is mostly caused by fatigue cumulative damage under the action of multi-level complex loads. Under complex loads, the sequence effect and coupling effect between loads have a significant impact on ...

A statistically self-consistent fatigue damage accumulation model including load sequence effects under spectrum loading [PDF]

open access: yesFracture and Structural Integrity, 2016
A probabilistic methodology is proposed to evaluate fatigue damage accumulation and fatigue lives of specimens under variable amplitude loading. With probabilistic modifications in the present model, the calculative consistency is achieved between ...

Influence of mechanical properties on load sequence effect and fatigue life of aluminium alloy

open access: yesJournal of Mechanical Engineering and Sciences, 2017
Most of the structural components in real applications are subjected to variable amplitude loading. The load sequence may have a significant effect on the number of cycles to failure. However, the relationship between the mechanical behaviour of material

MRKAd5 HIV-1 Gag/Pol/Nef vaccine-induced T-cell responses inadequately predict distance of breakthrough HIV-1 sequences to the vaccine or viral load. [PDF]

open access: yesPLoS ONE, 2012
The sieve analysis for the Step trial found evidence that breakthrough HIV-1 sequences for MRKAd5/HIV-1 Gag/Pol/Nef vaccine recipients were more divergent from the vaccine insert than placebo sequences in regions with predicted epitopes.

Short‐term load forecasting based on a generalized regression neural network optimized by an improved sparrow search algorithm using the empirical wavelet decomposition method

open access: yesEnergy Science & Engineering, 2023
With the development of the electric market, electric load forecasting has been increasingly pursued by many scholars. Because the electric load is affected by many factors, it is characterized by volatility and uncertainty, and it cannot be forecasted ...
