This paper reports a nonlinear finite element analysis of pressurized circular toroidal tank with radial flush cylindrical nozzle used for gas fuel tank of personal car. The analysis determines the position of radial cylindrical nozzle that gives the highest limit pressure. Toroidal tank having volume of 45 liters and radius ratio of 3 were used in this analysis. Cylindrical nozzle of 12.5 mm diameter and 10 mm height was attached in radial direction of toroidal cross section. The position of nozzle was checked for five points: extrados, 450 from extrados, crown, 450 from crown, and infrados. The maximum applied intemal pressure was 1.5 times pressure to yield. Limits pressure were obtained via nonlinear finite element analysis using the well-k•rown Newton-Raphson algorithm with large deformation. It was found that the best design for nonle position, indicated by the highest limit pressure, is located at the exfrados. For any circumstances, nozzle can be located between extrados and crown, but should not be located between crown and intrados. This result conforms to the membrane theory that the highest sfress in toroidal shell under intemal pressure occurs at intrados and nozzle shall not be located next to that location. Keywords: pressurized toroidal tank, limit pressure, finite element analysis
