Pressure Vessel Reinforcement Pad Design by Finite Element Analysis

This research aims to study and compare several reinforcement pad design or repad on a pressure vessels based on finite element analysis. Present study is focused on pressure vessel component such as nozzle, repad and shell to nozzle intersection area. Results from finite element analysis performed on repad from previous works were discussed. The repad design as outlined in American Society of Mechanical Engineers Boiler and Pressure Vessels Code were adopted by most researchers as reported in the literatures. Common repad configurations and findings from analysis were discussed. Results from previous studies on the effect of stress concentration factor, d/D ratio, effect of elastic stress and buckling effect on structure nozzle to shell junction were summarized in this paper.
