Metal Fatigue in Engineering

Metal fatigue is the weakening of a metal caused by repeated cycles of stress or loading, even if each load is below the metal’s breaking point. Over time, these repetitive stresses create tiny cracks that grow gradually, eventually leading to fractures or failure of the material. This process often occurs in structures like bridges, airplanes, and machinery. Understanding metal fatigue is crucial for designing durable components and preventing unexpected failures, ensuring safety and longevity of engineering systems.
