lifetime
analysis (
ex.Weibull
) types having five or more common mode failures with severity levels I to XII.
Infant-mortality failures (Weibull-shape parameter β < 1,0)
Random failures (β = 1,0) - human errors, foreign-object failures
Early wear-out failures (1,0 < β < 4,0) -low cycle fatigue, most bearing failures, corrosion and erosion
Old age wear-out failures (β ≥ 4,0)
