Forensic analysis is the art and science of applying metallurgical analysis, materials science, and failure analysis techniques to discover the failure mechanisms behind mechanical failures and the root cause of a failure. This paper will give the attendee the reasons for conducting a forensic analysis, an overview of the methods and procedures used in the forensic analysis of failed parts, and a discussion of instructions for field personnel when preparing and preserving failed parts for later analysis. The paper is based on the recently completed GMRC technical report of the same name.
