materiaaliväsymys
Materiaaliväsymys, also known as fatigue, is a phenomenon where a material weakens over time due to repeated stress. This weakening can occur even if the applied stress is below the material's yield strength. The process involves the initiation and gradual propagation of cracks within the material. These cracks start at microscopic flaws or stress concentration points and grow incrementally with each load cycle. Eventually, when the accumulated crack growth reaches a critical size, the material can fail suddenly and catastrophically.
The rate at which fatigue damage accumulates depends on several factors, including the magnitude and type of
Understanding and predicting material fatigue is crucial in engineering design, especially for components subjected to dynamic
