Understanding stress and strain is essential for structural design from "summary" of Aircraft Structures & Systems EASA Module 13 B2 by
To design a structure that can withstand the loads it will likely encounter during its service life, engineers need to have a deep understanding of stress and strain. Stress is the internal resistance generated within a material when it is subjected to an external force, while strain is the deformation that occurs in the material as a result of stress. By analyzing these two factors, engineers can predict how a structure will behave under different loading conditions. When designing aircraft structures, it is crucial to ensure that the materials used can withstand the stresses and strains they will experience during flight. Failure to do so can result in catastrophic consequences, not only for the aircraft but also for the passengers and crew on board. By understanding stress and strain, engineers can select materials that are strong enough to support the loads placed upon them while still being lightweight enough to meet performance requirements.
