FINITE ELEMENT ANALYSIS OF THIN WALLED PRESSURE VESSELS

In this study thin walled pressure vessels made from two different materials refered in ASTM standarts were analysed under pressure. Two and three dimensional finite element models were constructed by Ansys 9.0, three dimensional model was studied for two different designs. Failure analysis was performed with stress resultants. Burst pressures and critical areas were obtained by using maximum stress criteria. Failure resultants were compared with Von Mises yield criteria and analytical results of standarts. It was found that finite element models, design criterias and material properties are effective tools for analysis. The burst pressure results based on finite element analysis were found higher than the results of analytical solutions based on the standarts
