Modulus of Elasticity for Metals

Modulus of elasticity (or also referred to as Young''s modulus) is the ratio of stress to strain in elastic range of deformation. For typical metals, modulus of elasticity is in the range between 45 GPa (6.5 x 10 6 psi) to 407 GPa (59 x 10 6 psi). Modulus of elasticity is also a measure of material''s stiffness or resistance to elastic deformation.
