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 (force per unit area) and axial strain (proportional deformation) in the linear elastic region of a material and is determined using the formula: =

What Is The Young''s Modulus Of Steel?

Apr 16, 2021· The Young’s modulus of steel (also referred to as modulus of elasticity of steel) is between 190 – 210 GPa at room temperature, which is around 27500 ksi to 31200 ksi. The steel young modulus is a measure of its stiffness/ resistance elastic deformation to tensile loads. The reason for differing values of young’s modulus of steels is due to the manufacture process, which accounts for …
