I'm doing some spring endurance test.
If the spring is exceeding its cycles limit and causes fatigue failure, how normally the spring constant changes? For example, after the expected limit cycles (lets say 2million load-unload cycles), will the spring constant gradually decreases? or fluctuated as the cycles continue (after 2million)?
In simple words, how the spring constant changes (with cycles continue) if a spring is fatigue, creep or degraded? How to determine if a spring steel is degrading?
(Please assume everything is in ideal condition, as there are many factors might affect the result)
