Abstract
Probabilistic stress analysis of cylindrical pressure vessel under internal pressure is performed using FEA. The pressure vessel was modeled as an axisymmetric shell with symmetric boundary condition along the two unloaded edges. The loaded edges were treated as clamped in this study. Monte Carlo simulation technique is used to estimate the probability of failure of the cylindrical pressure vessel by considering uncertainties. Here variations in material properties and loads are assumed to follow the Normal distribution with 1 to 5% variations this analysis has been carried out by using PDS facility of ANSYS software. The ANSYS Probabilistic Design system (PDS) analyzes a component or a system involving uncertain input parameters. The probability of failure is calculated by applying the limit state equation. From that, the reliability of the pressure vessel component is estimated. This result is used to make a decision to produce a component for required reliability.
