Physics - 2B-2 Young Modulus

young modulus definition, eqn

Young Modulus

A measure of the stiffness of a material, defined as the ratio of tensile stress to tensile strain within the elastic limit.

Formula

Young Modulus = Stress/Strain

gradient

of the stress-strain curve, representing the material's stiffness.

area under grapn

of the stress-strain curve, representing the energy absorbed per unit volume before failure.
