Under cyclic loading, total lifetime reduction increases up to 7%.
Under cyclic loading, total lifetime could be reduced up to 7% by global warming action.
In order to facilitate the test and access to the loading and lifetime information of the power devices, a novel mission profile based stress emulator experimental setup is proposed and designed.
With increasing phase shift at the same equivalent load, the lifetime was found to increase.
The constitutive equations represent the materials properties mathematically and define the relationships between load, deformation, lifetime cycles, crack growth rates and stress intensities.
In particular, it appears that, for a given creep load, the lifetime of the material is increased if the volume fraction of fibers increases or if the length of fibers decreases, as long as the failure mode is fiber breakage.
Factors associated with sustained HPV exposure (abnormal cytology, elevated HPV viral load, increasing lifetime partners) were predictive of HPV-16 seropositivity.
Some of these units are the spherical joints for cars suspension which undergoing complex loading during its lifetime.
Realistic lifetime loading rates of methanogenic leachate were applied, and clogging was not generally apparent in any of the drainage media studied.
Additionally, the physiological window for knee health is thought to be highly individual and may be influenced by genetics, sex, lifetime loading history, presence of prior injury/scar tissue, systemic pathology, and local anatomy [15].
As Biewener proposed, the lifetime loading history is of central importance to this problem [42], along with the likelihood of traumatic fracture, fracture healing capacity, rate of fatigue accrual and repair and the animal's ability to cope with lameness of several weeks' duration.
