Optimal wall-thickness of the spherical pressure vessel with respect to criterion about minimal mass and equivalent stress

Stress distribution in the spherical vessel shell is calculated according to membrane shell theory. By using of the Mises strength theory, the functional relations of both equivalent stress and pressure vessel mass with wall thickness were defined. These two curves were presented graphically and their intersection point has been considered as an optimum point where both shell mass and equivalent stress are minimal. Demonstrated principle could be applied by optimization over the zones at huge spherical vessels design.
