What is Young's Modulus?
Young's modulus (E), also known as the elastic modulus or tensile modulus, is a measure of the stiffness of a material. It describes how much a material will deform under stress. A higher Young's modulus indicates a stiffer material that resists deformation. It is defined as the ratio of stress (force per unit area) to strain (relative deformation) in the linear elastic region of the stress-strain curve.
Young's Modulus Formula
Basic Formula
E = σ / ε
Where: E = Young's modulus, σ = stress, ε = strain
Expanded Formula
E = (F × L₀) / (A × ΔL)
Where: F = force, L₀ = original length, A = area, ΔL = change in length
