...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...

... analysis analyses were carried out at various loading rates. From the displacement profile, the crack tip opening displacements (CTOD) were calculated according to the principles of fracture mechanics. Comparing the dynamic values to the static result, a dynamic amplification factor (DAF) was obtained...
