“Comparison of limit load, linear and nonlinear FE analysis of a typical vessel nozzle”, (publisher and date not given in the pdf file. Latest reference is 2000. Paper probably published in 2001)
ABSTRACT: A limit load analysis of a vessel nozzle with pressure and external force loading was conducted. The limit load was defined by increasing the pressure and the nozzle external loads proportionally until collapse occurred. The evaluation of the limit load analysis was conducted in accordance with ASME BPVC Section VIII Division 2 [1]. The limit load analysis provides insight into the collapse load and failure mode. The results of the limit load analysis and a plastic analysis are compared to the results obtained by linear and nonlinear shell and plate element analyses of the same nozzle. The authors discuss the comparison of the results as there is some variance between the different methodologies.
