Young’s Modulus, often denoted as “E,” is a fundamental material property used in aircraft design and engineering. It quantifies a material’s stiffness or elasticity, specifically how it responds to axial or tensile deformation (stretching or compression) when subjected to an applied force.
The formula for Young’s Modulus (E) is defined as:
- E is Young’s Modulus, measured in pascals (Pa) or newtons per square meter (N/m²).
- Stress (σ) is the applied force per unit area (measured in pascals, Pa).
- Strain (ε) is the ratio of the change in length (deformation) to the original length of the material (dimensionless).
