In materials science, fatigue is the initiation and propagation of cracks in a material due to cyclic loading. Once a fatigue crack has initiated, it grows a small amount with each loading cycle, typically producing striations on some parts of the fracture surface.
Metal fatigue is a critical phenomenon that affects a wide array of industries, from aerospace to automotive and even oil and gas and consumer electronics. It refers to the gradual weakening of material due to repeated stress, which can eventually lead to failure.
Metal fatigue, weakened condition induced in metal parts of machines, vehicles, or structures by repeated stresses or loadings, ultimately resulting in fracture under a stress much weaker than that necessary to cause fracture in a single application.
7 de nov. de 2023 · Metal fatigue refers to the structural damage that occurs to material when subjected to cyclic loading. In this condition, the applied stress is repeated in a changing manner. This leads to the growth of cracks, potentially culminating in sudden failure without prior large-scale deformation or obvious deterioration.
1 de abr. de 2024 · Have you ever wondered why some metal parts fail unexpectedly? Fatigue strength, a critical factor in mechanical engineering, holds the answer. In this insightful article, we delve into the fascinating world of fatigue strength and explore the various internal and external factors that influence it.
The impact of mechanical fatigue on load-bearing metallic components and structures is highly significant, encompassing economy, environment and safety aspects. For nearly 200 years, engineers and scientists have been relentlessly trying to avoid fatigue failures and to understand their causes.
