If you type "incompressible surface" into Wikipedia, you get a math-related page. If you type in "compressible surface", it redirects to this (non-math-related) page. I suggest that either Compressible surface become a disambiguation page, or a link to Incompressible surface be given at the top of this page (since "compressible surface" redirects here).

"Physical compression is the result of the subjection of a material to compressive stress, resulting in reduction of volume." Adding compression to an expanding material will merely slow the expansion. —Preceding unsigned comment added by NOrbeck ( talk • contribs) 23:53, 23 July 2010 (UTC)
This article is linked to from Rarefaction as its "opposite". This article states the opposite of compression is tension and does not mention rarefaction at all. Continuity? —Preceding unsigned comment added by 144.137.115.195 ( talk) 01:54, 28 October 2007 (UTC)
The head claimed that "rarefaction" is the opposite of compression in fluids. That is not correct: rarefaction is a geometrical concept that does not involve forces explicitly. As such it is the opposite of "condensation", "addensation", or "volume contraction".
In sound waves the medium suffers rarefaction half of the time, but is under compression all the time.
The opposite of compression in fluids is rarely observed since most fluids will boil (cavitate) before the pressure gets reaches zero. Unlike solids, a macroscopic traction stress in a liquid does not get spread out over a gazillion atomic bonds, but becomes concentrated on a few bonds that immediately break (i.e. "boil"). Traction in fluids may be detectable for very short times, exploiting viscosity; I don't know. --

If the forces are inward, parallel, and balanced (equal), but not and alligned (on the same line), will there not be either a rotation, a shearing, or a twisting deformation, as opposed to the pinching deformation in compression? Or does "balanced" mean "equal, parallel, and alligned"? In any case, we should define "balanced", since it has many meanings, often in the same field.
