... torispherical domes that were in the past tested for burst. Hence, the relevance of matching material model is necessary for the finite elements (FE), analyses. In the past, plastic instability and constraints on the magnitude of plastic strains were postulated as criteria for the burst of internally...

.... That is because Monel 400 and other steam generator tube alloys are very ductile. The failure is controlled by the plastic instability. This ductile failure explains why a tube with an OD slot can be used to calibrate tubes with ID slots. If the failure mode is not plastic instability (when fracture mechanics...
