| Abstract: | In this study, the influence of nonuniformity of eccentricity of stringers on the general axial buckling load of stiffened
laminated cylindrical shells with simply supported end conditions is investigated. The critical loads are calculated using
Love’s First-order Shear Deformation Theory and solved using the Rayleigh-Ritz procedure. The effects of the shell length-to-radius
ratio, shell thickness-to-radius ratio, number of stringers, and stringers depth-to-width ratio on the buckling load of nonuniformly
eccentric shells, are examined. The research demonstrates that an appropriate nonuniform distribution of eccentricity of stringers
leads the buckling load to increase significantly. |
