A failure analysis is performed on metal objects that stop performing as required or fail to meet quality requirements. This video is a short discussion of the circumstances when a failure analysis is performed, the goals of a failure analysis, and the steps of a failure analysis.
Brass rivets were cracking during assembly, when the rivets were being set. Failure analysis of the rivets was performed as part of the process to determine the root cause of the cracking.
A stainless steel tool chuck was cracking during product assembly, affecting about 30% of all chuck. A failure analysis of the cracked chucks and analysis of the chuck design and manufacturing process was performed to determine the root cause of the cracking. This article discusses the findings and how the problem could have been prevented.
