RISReference Curve of Fatigue Crack Growth for Ferritic Steels Under Negative R Ratio Provided by ASME Code Section XI
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Reference curves of fatigue crack growth rates for ferritic steels in air environment are provided by the ASME Code Section XI Appendix A. The fatigue crack growth rates under negative R ratio are given as da/dN versus ...
Fatigue Crack Growth for Ferritic Steel Under Negative Stress Ratio
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The phenomenon of crack closure is important in the prediction of fatigue crack growth behavior. Many experimental data indicate crack closures during fatigue crack growths both under tensile–tensile loads and tensile–compressive ...
Improvement of Probabilistic Fracture Mechanics Analysis Code PASCAL-SP Regarding Stress Corrosion Cracking in Nickel Based Alloy Weld Joint of Piping System in Boiling Water Reactor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the past few decades, cracks because of stress corrosion cracking (SCC) have been detected in the dissimilar weld joints using nickel-based alloy in piping system of boiling water reactors (BWRs). Thus, the structural ...
Crack Growth Evaluation for Cracked Stainless and Carbon Steel Pipes Under Large Seismic Cyclic Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Some Japanese nuclear power plants have experienced several large earthquakes beyond the design basis ground motion. In addition, cracks resulting from long-term operation have been detected in piping systems. Therefore, ...
Technical Basis for Revising the Fatigue Crack Growth Rates for Ferritic Steels in the ASME Code Section XI
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fatigue crack growth thresholds ΔKth and reference fatigue crack growth rate da/dN curves for ferritic steels in air environment are provided in Appendix Y of the ASME Boiler and Pressure Vessel Code Section XI. Therein, ...
Development of Scaling Parameter SR for Negative Stress Ratios R Based on Trend in Experimental Data for Fatigue Crack Growth Rates of Austenitic Stainless Steels for ASME Code Section XI
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fatigue crack growth rates da/dN for stainless steels in air environment are provided by the ASME Code Section XI. The fatigue crack growth rates are given by da/dN = CF(ΔK)n, where CF is the fatigue crack growth rate ...
Experimental and Analytical Studies on the Effect of Excessive Loading on Fatigue Crack Propagation in Piping Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The seismic design review guide in Japan was revised in September 2006 to address the occurrence of a large earthquake beyond the design basis. In addition, Japanese nuclear power plants (NPPs) experienced multiple large ...
Improvement of Probabilistic Fracture Mechanics Analysis Code PASCAL-SP With Regard
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Probabilistic fracture mechanics (PFM) analysis is expected to be a rational method for structural integrity assessment because it can consider the uncertainties of various influence factors and evaluate the quantitative ...
