Young''s modulus - Wikipedia

Young''s modulus, the Young modulus or the modulus of elasticity in tension, is a mechanical property that measures the tensile stiffness of a solid material. It quantifies the relationship between tensile stress σ {\displaystyle \sigma } (force per unit area) and axial strain ε {\displaystyle \varepsilon } (proportional deformation) in the linear elastic region of a material and is determined using the formula: [1]
