mechanical hysteresis

mechanical hysteresis

[mi′kan·ə·kəl ‚his·tə′rē·səs]
(mechanics)
The dependence of the strain of a material not only on the instantaneous value of the stress but also on the previous history of the stress; for example, the elongation is less at a given value of tension when the tension is increasing than when it is decreasing.

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.
Several factors can affect the combustion process over time such as: Barometric conditions Calorific value Mechanical hysteresis.
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.
i] sum of corrections caused by internal influences (barometrical effect, mechanical hysteresis and other).
The mechanical hysteresis is the common effect which occurs after break (clamping/unclamping) between measurements.
Mechanical hysteresis tests were also performed at different maximum stress levels of 1.
The material can withstand extreme elongations with cracking or spalling and endure thousands of flex cycles with low 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.
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.
For all materials, even in a continuous and homogeneous cyclic loading-unloading process, there is typically a difference between deforming work and elastic recovery, which is the mechanical hysteresis.
