Title

Pressure Vessel Shell-Flange Fillet Weld Stress Concentrations by Finite Element Analysis

Abstract

Finite element analysis techniques are used to determine elastic stress concentration factors for several variations of pressure vessel shell to flange fillet welds. The axisymmetric finite element models allow both with and without metal-to-metal contact conditions outside the bolt circle to be considered. The stress concentration results are presented as dimensionless functions of fillet angle and weld cross sectional area. Plots are also given to show how the peak stress varies through the shell thickness at the critical intersection of the fillet weld and the cylindrical shell.
