Abstract
The fracture resistance and integrity of pressure-loaded components have been assessed in a Nordic research progranune. Experiments were performed to validate the computational fracture assessment analysis. Two tests were also
conducted on a large decommissioned pressure vessel from an oil refinery plant.
Different fracture assessment methods were developed and subsequently applied to the tested components. Interlaboratory round robin programmes with the participation of several laboratories were arranged to examine elastic-plastic
finite element calculations and fracture mechanics testing. The transferability of material parameters derived from small specimens with simple crack geometries to more realistic crack geometries in real components has been verified.
