Spring Fatigue

Premature spring fatigue can occur due to any number or combination of factors—the type of material and its strength, the stress conditions and rate of cyclic loading, surface quality, cracking, creep, or even manufacturing processes. If, for example, spring fatigue happens prematurely then it is likely that the stress on the material’s structural components was greater than the strength of the spring. The spring could not hold up to the cyclic loading as designed. During the design phase of springs, engineers will take into account these factors to ensure the spring will function over its operational lifespan as intended.
