Modulus of elasticity

The modulus of elasticity, which is also referred to as elastic modulus, elasticity coefficient, tensile modulus or Young's modulus, describes the relationship between tension and elongation of a solid body with linear elastic behavior in the event of deformation. The modulus of elasticity increases with the resistance with which a material counteracts the deformation. In other words, a material with a relatively high Young's modulus, such as steel, is relatively stiff, while a material with a relatively low Young's modulus, such as rubber, is relatively flexible.
