Young's modulus

Young's modulus is a relationship between elasticity, strain, and stress:

  • elasticity x (change in length / original length) = (force / area)

put another way, this is

  • elasticity x (strain) = stress

or

  • elasticity = stress / strain

The units of elasticity are in kPa.

This relationship is fundamental to strain elastography and shear wave elastography.
