Young's modulus - Wikipedia

Young's modulus or Young modulus is a mechanical property that measures the stiffness of a solid material. It defines the relationship between stress (force per unit area) and strain (proportional deformation) in a material in the linear elasticity regime of a uniaxial deformation.. Young's modulus is named after the 19th-century British scientist Thomas Young.
