Modulus of elasticity

The modulus of elasticity is a material parameter from materials engineering. It is often also referred to as tensile modulus, elongation modulus or Young's modulus.


It describes the relationship between stress and strain of a solid material in the linear elastic range. In simple terms, the modulus of elasticity is a characteristic value for how much a material yields when a force is applied. For example, rubber has a much lower value than steel. This means that under the same load and geometry, a component made of rubber yields much more than the component made of steel.

The calculation of the modulus of elasticity

E = σ / ε = const.

E - modulus of elasticity
σ - stats
ε - Elongation
