Abstract

Within the Nordic Countries a four-year research programme in the area of elastic-plastic fracture mechanics was initiated in 1985. Seven laboratories from Denmark, Finland, Norway and Sweden are participating in the programme. This programme aims to assess the leak-before-break (LBB) criteria for pressure vessels and piping. The major experimental effort of the programme is pressurization to rupture of large pressure vessels having dimensions resembling those of a nuclear reactor pressure vessel. The vessels used had been in operation for 20 years in a Finnish oil refinery plant. Artificial flaws were made on the inner wall of the vessels. The dimensions of the flaw were defined by calculations so that LBB condition was anticipated during the tests:

Part of the materials characterization of the pressure vessels was carried out as a Nordic round-robin programme. The first pressure test was performed at +60°C, which was the lowest acceptable temperature for the hydrotest. The instrumentation used in the test included e.g. strain gauges on inner and outer vessel wall, crack opening displacement measurement with clip gauges, potential drop measurements and acoustic emission testing. A second test is scheduled for the summer 1988.

The results of the test is reported and compared to calculations. The fracture behaviour is discussed.
