Probabilistic Failure Analysis
Many of the problems we solve involve significant uncertainties in the input variables. This is particularly true for advanced concepts or advanced technologies where new ideas are being exploited. A typical example is the use of an advanced high-temperature ceramic matrix composite material (CMC) such as silicon carbide in a turbine vane application. A traditional deterministic failure analysis concluded that a test specimen undergoing a life verification test would survive unconditionally. But a subsequent probabilistic analysis revealed a significant failure risk due to material property uncertainties. While a turbine vane failure during laboratory testing is not considered catastrophic, such a failure during normal operational usage would be.
