components have been assessed in a Nordic research programme.
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. | | Publication date: | 01 Nov 1989 | | ISBN: | ISBN: 87-7303-348-0 | | Number of downloads: | 10859 | | Download: |  102.PDF |
