Ickekompressibla
Ickekompressibla is a term used in Swedish-language science and engineering to describe substances or models that are effectively non-compressible. In practice, it denotes an idealization in which a material's volume remains constant when subjected to external pressure within a specified range. The term is commonly used for liquids and solids where density changes are small enough to be neglected in introductory analyses.
Origin and usage: The compound translates to "not compressible" and is used as an adjective and as
Theoretical implications: Incompressible materials are described by equations of state where density is constant; in fluid
Limitations: No real material is perfectly incompressible; compressibility becomes important at high pressures or large deformations.
