Young’s Modulus, also known as the modulus of elasticity, is one of the most important parameters of a material that describes its stiffness. Steel is one of the most commonly used materials in structural engineering. The value of Young’s Modulus for steel is 200-210 GPa. This means that steel is a material with high stiffness and resistance to deformation under load.
Formula for Young’s Modulus Young’s Modulus is defined as the ratio of stress to strain within the elastic range of the material (that is, how the material deforms under a load). Mathematically, Young’s Modulus can be expressed by the following formula:
\(E=\frac{\sigma}{\varepsilon}
\)
Where:
- E – Young’s Modulus,
- σ – stress,
- ε – strain.
This formula shows the direct relationship between stress, which is the force applied per unit area of the material, and strain, which is the relative change in the material’s length.
Application of Young’s Modulus for Steel Knowing the value of Young’s Modulus in the design of steel structures is extremely important. This parameter allows engineers to determine how much deformation can occur in a material due to applied loads. Accurate analysis of the structure enables precise design of structural elements such as beams, columns, and other load-bearing components, which in turn can prevent structural damage or unforeseen deformations.
The Young’s Modulus for steel is 200-210 GPa. This indicates that steel is a material characterized by high stiffness and resistance to deformation.
