COMPARISON OF NUMERICALLY AND EXPERIMENTALLY DETERMINED SCF FOR NOZZLE IN CYLINDRICAL PRESSURE VESSEL
In this paper the stress concentration factor for the case of set-on nozzle in a cylindrical vessel under internal pressure is researched. Two different nozzle geometries are investigated using numerical and experimental methods, FEM analysis performed in ABAQUS and strain gauges measurements. Based on numerical and experimental results, stress concentration factors defined by maximum principal and maximum von Mises equivalent stresses are calculated and compared. The comparison shows good agreement between the stress concentrations factors determined with the two different methods.
