FMEA: Predicting Failure Before It Happens

An FMEA that lives in a spreadsheet and never changes a design decision is not failure analysis — it is documentation theatre. A useful FMEA is a living tool that identifies the failure modes most likely to cause harm, ranks them by risk, and drives specific design or process changes to reduce that risk before the product reaches the customer. The difference between the two is in how the analysis is structured and what is done with the results.

Thermal Failure: Heat, Creep, and Thermal Fatigue

Thermal failures do not look like mechanical failures. A shaft that has crept out of tolerance shows no fracture, no visible damage, and no obvious cause for the dimensional change. A component that failed by thermal fatigue shows cracks that look like mechanical fatigue but propagate in a different pattern and require different corrective action. Recognising thermal failure mechanisms from their physical evidence is the starting point for prevention.
