loading cycles

loading cycles

In structural design, the number of repetitions of load assumed to act on a structure during its lifetime; used as a criterion in determining the fatigue strength of the structure.

The successive five compression cyclic loading cycles with no resting time on a TN gel at 80% strain was conducted, and the corresponding compression stress and dissipated energy of TN gels at different cycles were calculated (Fig.
Beginning of the fatigue fracture stage earliest, with a smaller number of loading cycles, is observed at [R.sub.[sigma]] = -1 and increases by several orders of magnitude when [R.sub.[sigma]] = 0.5.
Users can select single-material, ratio, volume, and time-fill loading, as well as an idle-mode valve, which allows the vacuum pump to continue running between loading cycles to reduce the number of pump stop-start cycles, which prolongs pump life.
A higher number of loading cycles to failure implicated a higher resistance to torsional failure of the instrument.
From Figure 3(a) it can be seen that, on all loading cycles, starting from III, the jumps of AE activity are clearly revealed when the load reaches the maximum of the preceding cycle.
If SMA rods without pretraining or with inadequate pretraining are used in a self-centering system, considering that the number of loading cycles and the strain amplitude in each loading cycle would being experienced by the SMA rods during an earthquake event could not be predicted in advance, the behavior of the self-centering system will become unpredictable.
The method accounts for the effect of variable-amplitude loading cycles. The hose is subjected to cycles of combined bending, torsion and internal pressure.
It combines a hydrostatic drive, which is ideal for short loading cycles, with a mechanical drive, which in turn shows its benefits when covering long distances.
When the crack approximately propagates to 0.5 mm, start to count the number of loading cycle. At the same time, the crack length was measured by per 9000 loading cycles.
To preform further analysis of the evolution of the preload during bolt self-loosening, the number of loading cycles is increased to 150 and the initial preload is set to 8 kN.
The release includes features for calculating self-heating, for analyzing rolling structures (e.g., tires and rubber rollers), and for diagnosing cavitation and wrinkling conditions that might occur during loading cycles. The features are provided at no additional cost under the existing license.
