The purpose of this work is to investigate the elastic stress and deformation of pressurized cylinders with a hillside nozzle. Two full-scale test models were designed and fabricated specially for the test. A 3D finite element numerical analysis was also performed. The elastic stress distribution, stress concentration range, deformation characteristics, and stress concentration factor were obtained. The elastic results show that the distinct stress concentration occurs on the hillside-nozzle intersection, and the intersection shrinks in the longitudinal section of cylinder, while a bulge appears in the transverse section. The range of stress concentration of the hillside-nozzle intersection in the transverse section of the cylinder is larger than that in the longitudinal section and the stress concentration factor declines with the increment of the angle . The results will serve as the basis for developing a design guideline for pressurized cylinders with various angles of the hillside nozzle.
