Kraus, H

The third in the series of three PVRC benchmark problems concerning elevated temperature design analysis technology is presented. The other two problems are presented in the three preceding papers in this publication. This problem is referred to as the Oak Ridge Nozzle to Sphere Attachment and the conditions, material properties, and a reference analytical solution were provided by the Oak Ridge National Laboratory. The problem involved a circular cylindrical nozzle attached to a hemispherical shell that is subjected to internal pressure, axial nozzle loads, and thermal transients. Detailed finite element solutions and analytical solutions by simplified methods were provided to the PVRC. The results are compiled, summarized, and compared with one another in this paper. Experimental results were not available for comparison. Greater consistency might have been expected between the analytical results, but the geometric approximation made by the analysts were concluded to give conservative predictions.
