Glossary:Modulus of elasticity
Stress over strain. A measure of stiffness or Young’s Modulus (E). Rocks are ½ to 12 x 106 psi and mild steel is 30 x 106 psi. Modulus refers to stress at a predetermined level of elongation, usually at 100% elongation. The higher the modulus of a compound, the more apt it is to recover from loading or localized force and the better is its resistance to extrusion.
