Sentence examples for under variable fatigue from inspiring English sources

A pattern of increased fatigue life with a reduction in loading frequency under variable fatigue was observed.

Finally some applications to lifetime prediction under variable amplitude fatigue loading are presented.

Experiments are performed under variable amplitude fatigue loading in order to calibrate and verify the validity of the model.

A user defined material subroutine is used in the ANSYS finite element code to predict both the crack (debonding) initiation and propagation in the adhesive joint under variable amplitude fatigue loading.

Further, such a computational efficiency is seen to be associated with an high-level of accuracy in estimating fatigue lifetime of both plain and notched engineering components, this holding true under constant as well as under variable amplitude uniaxial/multiaxial fatigue loading.

Furthermore, the mechanism of crack evolution under variable amplitude thermal fatigue was discussed.

The Kandil-Brown-Miller parameter and Fatemi-Socie parameter are comparatively studied in the perspective of application to multiaxial fatigue under variable amplitude loads.

Fatigue under variable amplitude loading is currently assessed with the Palmgren-Miner rule in structural standards, ignoring the order of loading, which would require non-linear or mixed rules, especially for the random loading sequences applied to certain structures.

In Eurocode standards, three verification schemes are proposed for fatigue design under variable amplitude loadings: 1) Based on constant amplitude fatigue limit; 2) Based on constant amplitude equivalent stress range at 2 ⋅ 106 cycles; 3) Based on accumulated damage.

There also exist two distinct regimes of crack growth behavior over the range of loading frequency from 5.0 × 10−1 Hz to 10−5 Hz under such variable amplitude fatigue.
