Quantifying Fitness-For-Service – Article by Bill O’Donnell, Sr.

Fatigue in welded steel components is often initiated by mechanical vibration, corrosion, and thermal cycling. Fitness-for-Service analysis is the most viable step in determining the safety and financial risk factors related to component repair or replacement. This Stainless Steel World article (written by Bill, O’Donnell, Sr.) shares insight about managing risk specific to weld failures.

As President of O’Donnell Consulting Engineers, Inc., he began his professional career at Westinghouse Bettis Atomic Power Laboratory, where he helped develop components for the nuclear Navy under Admiral Rickover. He has extensive professional experience in the analysis of components including fatigue and fracture safety evaluations and failure analyses. He has developed methods for evaluating fatigue, stress corrosion cracking and safety margins of components, and is an expert in complex failure modes which occur under cyclic loads.
