INFLUENCE OF GEOMETRY OF PRESSURE VESSEL NOZZLE CONNECTION ON STRESS CONCENTRATION FACTOR

The main objective of this paper is the numerical analysis and assessment of stress concentration in nozzle connection area of one pressure vessel used in petrol industry. The pressured vessel geometry was modeled in 3D modeling software and then model was used for determination of stress concentration factor using finite element method. Solution convergence was carried out to determine the optimal mesh density, and then the numeric calculation is performed using varying different geometry parameters of pressure vessel and nozzle connection. The results are processed and results are presented in form of diagrams.
