Fatigue reliability updating using NDE

Research output: Contribution to conferencePaper

Abstract

Using a linear elastic fracture mechanics (LEFM) approach, the fatigue reliability is estimated considering all major sources of uncertainty, including uncertainties in nondestructive inspection outcomes. The fatigue reliability is then updated using uncertainty-filled information from nondestructive inspections, as it becomes available. The updated information on the reliability is used as a decision making tool regarding what to do next, in terms of whether to do nothing, reschedule the next inspection to an earlier data, or immediately repair or replace the damaged element. The procedure is explained with the help of an example.
