bathtub curve the bathtub curve hazard function blue upper solid line is a combination of a decreasing hazard of early failure red dotted line and an increasing hazard of wearout failure yellow dotted line plus some constant hazard of random failure green lower solid line, the bathtub curve consists of three periods an infant mortality period with a decreasing failure rate followed by a normal life period also known as useful life with a low relatively constant failure rate and concluding with a wearout period that exhibits an increasing failure rate

The Bathtub Curve Its Not Really That Clean Cut

the muchquoted bathtub curve is an example of the practice of treating more than one failure type mode by a single classification it seeks to describe the variation of failure rate of components during their life, bathtub curve a plot of the failure rate over time for most products yields a curve that looks like a drawing of a bathtub if enough units from a given population are observed operating and failing over time it is relatively easy to compute weekbyweek or monthbymonth estimates of the failure rate
