ABSTRACT:
A system and method for determining remaining fatigue life of a component experiencing stress/strain cycles. In one embodiment the fractional life expended per clock cycle of the component is determined and multiplied by a data type value indicating whether a full cycle, half cycle or no stress/strain amplitude information was present during a given clock cycle. The product is then summed with the result of the previously clock cycle, to produce a running total of the fractional life expended. The running total is then subtracted, at each clock cycle, from an initial fatigue life value, and the output represents the residual fatigue life remaining for the component.
