Young's Modulus (E) is a measure of the stiffness of any material. It is also known as the Young Modulus, Modulus of Elasticity (MOE), Elastic Modulus or Tensile Modulus and is defined as the ratio of the uniaxial linear Stress over the uniaxial linear Strain in the range of stress in which Hooke's Law holds. This can be experimentally determined from the slope of a stress-strain curve created during destructive tensile tests conducted on a sample of the material. DEPA V9 determines the Young.
