Probabilistic Fracture Mechanics

A practical seminar on Probabilistic Fracture Mechanics used for such highly complex assessments as material fracture toughness and weld residual stress. Course covers fundamentals of both fracture mechanics and multi-variable probabilistic analysis, and includes discussions of case studies. Probabilistic codes Viper©, RRingLife©, and pc-CRACK© will be reviewed, in addition to the general statistical-analysis code, @RISK.

Peter Riccardella has a PhD in Mechanical Engineering from Carnegie Mellon University, and over 30 years of experience in design and analysis of large structural components. He is an authority on application of fracture mechanics to pressure vessel and piping problems, notably feedwater system thermal fatigue cracking, stress corrosion cracking in power plant piping, and pressure vessel embrittlement and pressurized thermal shock. Riccardella pioneered the development of flaw evaluation procedures and acceptance standards for ASME's Nuclear In-Service Inspection Code.

David Harris has a PhD in Applied Mechanics from Stanford University, a BS and MS in Mechanical Engineering from the University of Washington, and 40 years of experience in experimental and analytical fracture mechanics. Harris has developed probabilistic and deterministic life prediction software, including the NRC's PRAISE Probabilistic Fracture Mechanics-based software for nuclear reactor piping reliability, NASA's NASCRAC fracture mechanics software, and EPRI® TULIP© continuum creep damage mechanics-based software for superheater/reheater tube reliability.

Dilip Dedhia has a PhD in Materials Science from the Oregon Graduate Center and over 30 years of experience in deterministic and Probabilistic Fracture Mechanics analyses. Dedhia's particular expertise is in fracture mechanics methods, including high-temperature creep fatigue crack growth. He was co-developer of EPRI® BLESS© code for headers and pipes as well as co-developer of EPRI's TULIP© for high-temperature tubing. Dedhia also developed SI's pc-CRACK© 4.0 for general-purpose fracture mechanics analysis.
