RISA Probabilistic Model for Forging Flaw Crack Nucleation Processes for Heavy Duty Gas Turbine Rotor Operations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We present a probabilistic model for quantifying the number of load cycles for nucleation of forging flaws—for a 3.5NiCrMoV high strength low alloy rotor steel—into a crack under gas turbine operating conditions. The model ...
A Probabilistic Model for Forging Flaw Crack Nucleation Processes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A probabilistic model for quantifying the number of load cycles for nucleation of forging flaws into a crack has been developed. The model correlates low cycle fatigue (LCF) data, ultrasonic testing (UT) indication data, ...
