Fatigue design

Fatigue design involves creating structures and components that can withstand repeated loading and unloading cycles without failing over time. Every time a material experiences stress—such as bending, tension, or compression—it may develop tiny cracks. Repeated stress gradually widens these cracks, potentially causing sudden failure. Fatigue design aims to identify safe load limits and material choices to prevent such failures, ensuring durability and safety under cyclic use. This approach is essential in engineering fields like aerospace, automotive, and bridges, where components face continuous or repetitive forces throughout their lifespan.
