RISFailure Prediction of Curved Wide Plates Using the Strain Based Failure Assessment Diagram With Correction for Constraint and Notch Radius
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The strainbased failure assessment diagram (SBFAD) has been developed for predicting failure from flaws in components subjected to high plastic strains. In this paper, a combined numerical and experimental approach is used ...
Sensitivity of Plastic Response of Defective Pipeline Girth Welds to the Stress Strain Behavior of Base and Weld Metal
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: One of the key parameters influencing the acceptability of a pipeline girth weld defect subjected to remote plastic deformation is the strength mismatch between weld and base metal. However, no single definition exists for ...
Weld Strength Mismatch in Strain Based Flaw Assessment: Which Definition to Use?
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Weld strength mismatch is a key factor in the strain based assessment of flawed girth welds under tension. A strength overmatching weld shields potential flaws within the weld itself from remotely applied deformations and ...
Framework for Key Influences on Tensile Strain Capacity of Flawed Girth Welds
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A key influence factor in the strainbased assessment of pipeline girth weld flaws is weld strength mismatch. Recent research has led to a framework for tensile strain capacity as a function of weld flow stress (FS) overmatch. ...
