WebThe Poisson's ratio ν is always less than 0.5. A traction force ( Δ L > 0) can cause an increase in volume, while a compression force ( Δ L < 0) can only decrease the volume. Δ V ≈ V Δ L L ( 1 − 2 ν) I'm totally ok with these facts … WebCompressibility. In thermodynamics and fluid mechanics, the compressibility (also known as the coefficient of compressibility [1] or, if the temperature is held constant, the isothermal compressibility [2]) is a measure of the instantaneous relative volume change of a fluid or solid as a response to a pressure (or mean stress) change.
