Finite element method pressure vessel calculation and analysis of the effects of the butt welded joints on a carrying capacity of a structure

Abstract

In present paper, after calculation using the finite element method (FEM), stress distribution on the model of a part of the pressurized boiler shell without welded joints (WJ), with transversal WJ, longitudinal WJ and crosspoint location of WJ Is analyzed. Also, FEM calculation and comparative analysis of the effects of WJ on the stress distribution have been conducted using the tank for liquid carbon dioxide as an example, on which. In addition to the shell sheet-metal and heads with necessary openings and elements such as saddles with supports and hangers, transversa! and longitudinal butt WJ, have been modelled.
