Young's
Modulus (sometimes
referred to as Modulus of Elasticity, meaning "measure" of elasticity)
is an extremely important characteristic of a material. It is
the numerical evaluation of
Hooke's Law, namely the ratio of stress to strain (the
measure of resistance to elastic deformation).
To calculate Young's Modulus, stress (at any point) below the
proportional limit is
divided by corresponding strain. It can also be calculated as
the slope of the straight-line portion
of the stress-strain curve.
