FMEA Tip of the Month. high impedance? By. The degradation modes common to cooled hot-section superalloy components include low-cycle thermal fatigue, oxidation, and creep, with creep being the least important factor because it is designed out. | Minitab can analyze systems with multiple failure modes. _ Neglecting to tailor the list of failure modes to your application type Neglecting to filter/rank the code by risk and impact Assuming that hardware redundancy will prevent all software failure modes Neglecting to decide on the best viewpoint before doing the analysis. As used in pipeline safety regulations, an incident is an event occurring on a natural gas pipeline for which the operator must make a report to the Office of Pipeline Safety. A piece part FMEA will focus on detailed part or component failure modes (such as fully fractured axle or deformed axle, or electrical contact stuck open, stuck short, or intermittent).
