Abstract(s) :

(Anglais) Sometimes, failure is very difficult to explain, with root complex root causes linked to production, installation, use, maintenance and unexpected phenomena. Those presented in this review were not. None of those parts should have made it past process control (or even design for some) to end in industrial applications. Here is a review of some of our best doomed cases: parts that did not have any change of keeping physical integrity during use. Why did this screw crack all around its diameter? What made this washer break? And this fire extinguisher, why has it lost pressure? Because they were not carefully designed and processed.
