loops were conducted in order to understand the visco-elastic properties of the tested materials.
This leads to understand that mechanical hysteresis
provokes electrical hysteresis.
UCSF's control manager discovered that the pressure-independent venturi-type (mechanical) airflow control valves installed at each terminal in the building have a tendency to "wind up." That is, as their springs compress to limit airflow, a finite percentage will overshoot and cause airflow to measure slightly low due to mechanical hysteresis
. The phenomenon is more apparent at the desirable lower system static pressures and decreases with rising pressure.
Both curves (front and back) obtained by the ML10 laser have the same tendency, and they exhibit an offset in the form of mechanical hysteresis
behavior, primarily reflecting geometrical errors and the guiding bridge CMM relative to the y-axis.
This procedure is repeated cyclically so that the optimum working points are always maintained even for un-stable barometric conditions, mechanical hysteresis
or fluctuating calorific values.
The use of an LVDT for probe shaft displacement sensing eliminates any additional transducer errors due to friction, stiction or mechanical hysteresis
. The BB Series also offer unusually long life of 2 x 108 cycles.
where [??] is the reading in [CU], k the given scale factor, [k.sub.0] the additional scale factor, [summation][O.sup.I.sub.i](t) sum of corrections caused by external influences (Earth and ocean tides, air pressure changes and other) and [summation][O.sup.II.sub.i] sum of corrections caused by internal influences (barometrical effect, mechanical hysteresis
This makes it very difficult to separate long-term mechanical hysteresis
drift from thermal gradient signals.
During the strain cycle, energy is absorbed by mechanical hysteresis
. Clearly if the intrinsic adhesion is feeble, so will be the degree of elastomeric deformation and inversely strong adhesion leads to more bulk elastomeric strain.
tests were also performed at different maximum stress levels of 1.5, 2.5, and 15 kPa, at a constant strain rate of 3.03 E-2 [s.sup.-1].
Although van Wyk's theory is considered to be the most realistic, many authors have pointed out in their articles the weakness of the theory since it does not explain the irrecoverable strain during initial compression and the mechanical hysteresis
when the fiber mass is subjected to compression-release cycling.
