Abstract
According to anisotropic shell theory, the pressurized structure of cylindrical shell and spherical head is analyzed, and the shear force, bending moment and stress solution at the juncture are obtained. The influence of anisotropic mechanical properties and geometric parameters on shear force, bending moment and stress distribution along the cylindrical shell is discussed, and the results are compared with the isotropic results. Additionally, Hill48 anisotropic yield criterion is also used to derive the equivalent stress intensity expression of the plane stress state, and the effect of thickness ratio and elastic modulus ratio on Hill48 equivalent stress at the juncture is discussed. Finally, finite element method is applied to verify the results of stress intensity calculation, which shows that the finite element solution and the analytical solution are in good agreement.
