Our system (GPS) will monitor their fitness level, measure hundreds of physical metrics including distance, speed, acceleration, deceleration, high-speed running, and dynamic stress
The Series FT-3130 constant stress/strain fatigue tester applies dynamic stress
or strain on test pieces, and gives repeated tension at a fixed stroke to count number of strokes until the test piece is broken.
Researchers note that the system counts only one type of aftershock triggering when predicting, rather than accounting for static and dynamic stress
The high speed of 400 m/min actually simulates the dynamic stress
on the yarn during weaving, and this makes the USTERA(r) TENSOJET 5 a unique tensile measuring system.
The dynamic stress
is calculated based on the acceleration and the stress scale factor related to the vibration analytical model.
An approach based on the combined use of the boundary integral equations method and time Fourier transform is developed, which makes it possible to investigate the dynamic stress
state of media with microstructure weakened by tunnel cavities of arbitrary cross-section during the action of dynamic  and impulse  load, which is applied to the boundary of the cavity.
Comparing the values of the dynamic yield stress in Figure 24 to the dynamic stress
distributed over the cross section of the columns shown in Figures 20-23 reveals that most of the columns had not reached the full dynamic yielding capacity when the global failure occurred.
The dominant sources of phase error are phase jitter which is mainly caused by thermal noise and dynamic stress
error which is caused by relative motion between the receiver and satellites .

With this principle, the static and dynamic stress
can be perceived.
At 1.890% of strain, strain-thickening behavior (both storage and loss moduli showed a slight increase to higher level that was strain specific) under dynamic stress
was observed for the filled PDMS suspensions studied in the context.
