Proceedings of the ASME Pressure Vessels and Piping Conference,July 23-27, 2000, Seattle, Washington. Volume of 24 full-length,peer-reviewed technical papers address the unresolved issues in theareas of material degradation, failure and life prediction undercomplex operating conditions. Sampling of contents includes: AMultiaxial Theory With Consideration of Mean Stress Effects;Fatigue Performance of Flux-Assisted Inert Gas Girth Welded Piping;Use of Miniature Specimens for Creep Crack Growth Testing; FuzzyPattern Recognition for Mechanical Properties of Materials;Constraint Effect and Crack Curving Under Mode I Conditions; TemperEmbrittlement and Carbide Behavior of CrMo Steels forHydroprocessing Reactor Under 50,000 Hours Isothermal Aging. @By:R.
