Mechanical Falure Rates

[hysch]

Any references for mechanical Failure Rates, particularly for static components (eg_ chassis parts, mount and locing parts, guides etc.)?

Unless there's some sort of repetitive stress or overloads, there really should be no failures to speak of.

The dominant issue of mechanical failure and life prediction in engineering parts is fatigue failure of which repetitive load(lower that the static safety load) cause initiation, propagation and final destructive rapid growth of crack in engineering parts.

As far as I know, Palmgren-Miner Linear Damage theory is preferred by many to predict life due its simplicity as long as quasi-random stress level prevails in the fatigue process.
