Abstract

The manufacturing and testing procedures for two experimental pressure vessels with large nozzles encroaching into the knuckle region of the vessel head are described. Experimental linear elastic stress levels and plastic loads for pressure and combined axial and in-plane bending nozzle loads are compared with predicted values determined using non-linear finite element analysis. The quality of the results are considered to justify the procedures developed by the authors to conduct a parametric study of the individual limit loads and their interaction for these complex structures.
