Has anyone else read the case analysis of that gear failure that ultimately led to a major shift in industry standards for [Material Type] gears? It's fascinating (and a little terrifying) how a single point of failure, due to unexpected [Failure Mechanism], could have such a widespread impact.
The analysis detailed how the initial investigations focused on surface fatigue, but eventually pinpointed a subsurface inclusion as the actual root cause. That discovery forced a re-evaluation of non-destructive testing methods and substantially increased the rigor of quality control processes related to the alloy composition across the [Industry Sector] sector. Makes you wonder how many othre seemingly minor component failures are just ticking time bombs waiting for the right analysis!
I'm curious to hear if anyone working in related fields has seen similar changes implemented as a direct result of this (or other) high-profile incidents? Were these changes effective, or did they just add unneeded cost and complexity?
