The present work involved the Finite Element Analysis of existing LPG gas cylinder to verify the burst pressure. The LPG gas cylinder is manufactured from low carbon steel. The LPG tanks are subjected to incremental internal uniform pressure in the FEA model. 2D nonlinear plane models are developed and evaluated under non-uniform and axis symmetric boundary conditions. For the analysis, the required actual shell properties including weld zone and thickness variation are investigated. Therefore the stress distribution has been analyzed using ANSYS 11 software for which maximum shear stress, equivalent shear stress at critical area has been calculated. Therefore 3D solid model has been chosen in order to predict the detailed stress.
