Young's modulus

Andrew Murphy and Dr Matt A. Morgan et al.

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


  • elasticity = stress / strain

Elasticity is measured in kilopascals (kPa).

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

The Young's modulus can be calculated as 1

Young's modulus, E = 3 x tissue density x (shear wave velocity) 2
