Modulus of Elasticity
Modulus of Elasticity is the measurement of stiffness and rigidity of spring material, or its elastic ability. The higher the value (modulus), the stiffer the material. Conversely, materials with lower values are more easily bent under load. The Modulus (G) for extension and compression springs

when localized stresses exceed material strength. Typically, elastic behavior is linear right up to the fracture point. Moreover, they usually have high moduli of elasticity, which results in fracture at relatively small strains. Several companies are conducting research programs aimed
