Probabilistic Fracture Mechanics (PFM) analysis takes conventional deterministic fracture mechanics analysis a step further, using selected random variable inputs for situations that involve a significant degree of uncertainty — such as in crack size, or scatter in test results — and PFM analyses usually yield a failure probability, rather than a specific calculation of crack size or lifetime. Structural Integrity Associates, Inc. (SI) has applied PFM analysis to piping, reactor-head penetration nozzles, and other nuclear plant components. Many of SI's PFM analyses employ WinPRAISE^©, originally developed under NRC sponsorship: SI's latest version of the software, WinPRAISE 07, can analyze crack initiation and growth due to fatigue, IGSCC, PWSCC, and flow-accelerated corrosion. WinPRAISE is also available for purchase from SI in easy-to-use Microsoft® Windows® format.
