Study of crack initiation--arresting conditions in pressure vessel models with respect to accumulated energy
From 2nd international congress for pressure vessel and piping technology; San Antonio, Texas, USA (1 Oct 1973). See CONF731003-P2. An extensive research effort was performed for studying the safety criteria in nuclear reactor pressure vessels. The last four years of research work are described and the most importani results from this study discussed. An analysis is presented of the influence of accumulated energy in the pressurizing medium on the crack arrest temperature, which is taken as the basic criterion for pressure vessel (or pipeline) safety. Analysis of all results shows that at some characteristic temperature cracks, either brittle or fast shear, are arrested. Comparison of this temperature with other temperature criteria is introduced.
