RISRecharacterization of Subsurface Flaw to Surface Flaw Based on Equivalent Fatigue Crack Growth Rate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A subsurface flaw located near a component surface is transformed to a surface flaw in accordance with a flawtosurface proximity rule. The recharacterization process from subsurface to surface flaw is adopted in all ...
Fatigue Crack Growth Thresholds at Negative Stress Ratio for Ferritic Steels in ASME Code Section XI
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Thresholds of fatigue crack growth rates are important characteristics for fatigue crack growth assessment for the integrity of structural components. ASME Code Section XI provides fatigue crack growth thresholds for ...
Stress Intensity Factors for Transformed Surface Flaws and Remaining Fatigue Lives Based on Flaw-to-Surface Proximity Rules
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Subsurface flaws are sometimes found as blowholes near free surfaces of structural components. Net-section stress at the ligament between the free component surface and the subsurface flaw increases when the ligament size ...

Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Thresholds of fatigue crack growth rates are important characteristics for fatigue crack growth assessment for the integrity of structural components. ASME Code Section XI provides fatigue crack growth thresholds for ...
Plastic Collapse Stresses Based on Flaw Combination Rules for Pipes Containing Two Circumferential Similar Flaws
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When discrete multiple flaws are in the same plane, and they are close to each other, it can be determined whether they are combined or standalone in accordance with combination rules provided by fitness-for-service (FFS) ...

Allowable Cracks Related to Penetration for Part-Through Cracks in Pipes Subjected to Bending Stresses
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fully plastic collapse stresses for circumferentially part-through cracked pipes subjected to bending stresses are estimated by limit load criteria provided by the ASME Code Section XI. Allowable crack depths were determined ...
