incompressibility
- noun
- /ˌɪnkəmˌprɛsəˈbɪlɪti/
- Specialized
- The incompressibility of the material ensures that it maintains its volume even when subjected to extreme conditions.
Examples
-
Engineers must account for the incompressibility of gases when designing systems that operate under high pressure.
-
To obtain the initial modulus E, a Poisson's ratio of 0.5 was assumed to simulate the initial apparent incompressibility condition of the tissue as a whole.
Academic text (1994) -
OK, So what does this incompressibility condition mean?
-
Don't worry about the answer is that the incompressibility does not imply Hamilton's equations.
-
It is due to the fact that the three-point integration puts a higher incompressibility constraint into the mesh.
-
Constant dilatation formulations, which enforce incompressibility on an element level, resulted in artificially high pre-stresses in response to prosthetic socket rectification (13).
Academic text (1996) -
In fluid dynamics, the incompressibility of a liquid means it cannot be compressed into a smaller volume under pressure.

Morphology
incompressibility = incompressible (transparent) = in + compress + ible + ity
This is a regular noun formation from the adjective 'incompressible' meaning the state or quality of being incompressible.
Etymology
Incompressibility comes from in- meaning 'not' and compress meaning 'press together', and it shares this root with the word press. So it literally means 'cannot be pressed smaller', which is why we use it for materials that do not reduce in volume under pressure.
