It is a mistake to assume that the failure of any component is necessarily due to poor design or manufacturing flaws. Failures can be caused by a very large...

The fund of information that can be generated from these tests is phenomenal and is extremely useful to pinpoint the cause, mechanism, and sequence of the failure event. A separate chapter is devoted to cover these details. 3.6...

... failure mechanisms, the focus here is on what can cause a system to fail. System failures can be induced by component failures (such as the ones mentioned previously), or they can occur as a result of complex component and subsystem interactions (without any parts failing). Finding the root causes...
