Modulus of elasticity

The modulus of elasticity, also known as Young's modulus, tensile modulus, coefficient of elasticity, strain modulus or Young's modulus, characterizes the relationship between stress and strain during the deformation of a solid body with linear elastic behaviour. The formula symbol for the modulus of elasticity is E. The dimension of the modulus of elasticity is the mechanical stress with the units N/mm² or MPa (megapascal).
