In aircraft design, stress refers to the internal resistance of a material to deformation when subjected to an external force or load. It quantifies how the material responds to forces and is essential for ensuring the structural integrity of aircraft components.
The formula for stress (σ) is defined as
- σi s the stress in pascals (Pa) or newtons per square meter (N/m²).
- F is the force applied to the material in newtons (N).
- A is the cross-sectional area over which the force is applied in square meters (m²).
