Physics:Swelling index

From HandWiki

Swelling index may refer to the following material parameters that quantify volume change:

  • Crucible swelling index, also known as free swelling index, in coal assay
  • Swelling capacity, the amount of a liquid that can be absorbed by a polymer
  • Shrink–swell capacity in soil mechanics
  • Unload-reload constant (κ) in critical state soil mechanics
