would you weaken or shorten the life span of a compression spring by leaving it under a load for extended periods?
Corrosion can accelerate when a material is under stress, so yes, it's possible. Creep will also be significant at sufficiently large temperatures and times.would you weaken or shorten the life span of a compression spring by leaving it under a load for extended periods?
The spring may plastically (i.e., permanently) deform upon the first cycle. After that, creep will occur to some degree as long as stress is applied. Additionally, crack growth (i.e., fatigue) may occur with cycling. It's impossible to estimate the severity of these two effects without more information (and may be impossible without doing experiments on the sample).thanks for your answers,
does the spring reach a full set after one cycle?
does it continue to set thru repeated cycles?
do you think it helps to leave it under a load for a bit to reach it's full set?
