The modulus of elasticity, often denoted as “E,” is a fundamental material property that quantifies how a material responds to deformation (stretching or compressing) when subjected to an applied force or load. It measures a material’s stiffness or rigidity. In aircraft design, it is crucial to consider the modulus of elasticity when selecting materials for various components to ensure they can withstand the required loads and stresses.
The formula for the modulus of elasticity (E) is as follows:
- E is the modulus of elasticity (measured in pascals, Pa).
- Stress (σ) is the force applied to the material 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).
