... Section VIII Div 2. Finally, some of the implications on fracture mechanics based remaining life assessment for tubular joints are discussed in light of the results obtained in this investigation. Traction-based structural stress definition with respect to chord wall in a tubular joint: ( a ) 2D...

...Hugo A. Ernst; Richard E. Bravo This work studies the effect of the yield ( Y ) to tensile ( T ) ratio, Y ∕ T , on the structural integrity of line pipes with part through the thickness (PTT) circumferential defects subject to bend loading. A model based on elastic-plastic fracture mechanics...

... on elastic-plastic fracture mechanics and plasticity theory was developed for that purpose. The analysis allows for load or deformation control situations. The results are shown in terms of curves of critical defect size versus the controlling variable, i.e., load or deformation. For each one of the several...
