Mechanical Falure Rates

Mechanical Falure Rates

Mechanical Falure Rates

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

RE: Mechanical Falure Rates

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

RE: Mechanical Falure Rates

The reliability ananlysis center RAC publishes documents focused on military applications but also usful for any system made of discrete devices

RE: Mechanical Falure Rates

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.
