Young's Modulus
| Formula / Notation | E = σ × ε; σ = F/A; ε = ΔL/L₀; units: Pa |

| Also Known As | Elastic modulus, tensile modulus, modulus of elasticity, E-modulus |
What is Young's Modulus?
A measure of the stiffness of an elastic material (tensile elasticity), defined as the ratio of tensile stress to tensile strain. Measured in pascals (Pa). Materials with high Young's modulus (like steel, diamond) are stiff; those with low values (like rubber) are flexible.

Young's modulus is used by engineers to select materials for structural applications requiring specific stiffness. It is used to model the deformation of beams, columns, and pressure vessels under load. In biomechanics, the elastic modulus of biological tissues is important for designing implants an…
Materials with low Young's modulus are more easily deformed and may fail under unexpected loads. Brittle materials (high modulus, low ductility) can fracture suddenly without warning. Proper material selection based on Young's modulus prevents structural failures.
The formula or notation for Young's Modulus is: E = σ × ε; σ = F/A; ε = ΔL/L₀; units: Pa
