  Hydrostatic strain is the scalar quantity whose magnitude is the average of three normal strains. Hydrostatic strain only contributes to the volumetric change of a body and does not cause any shear deformation. It is also often expressed in a matrix form with only three diagonal terms.

  Hydrostatic strain, also called volumetric strain or dilatation, is strain that is equal in all normal directions, with no shear components. It is a change in the volume of a body, but not its shape.
