The Implementation of the Single Perturbation Load Approach to Axially-Compressed Stiffened-Stringer Cylinder

This work study the influence of imperfections on axially compressed stiffened-stringer cylindrical shells for different geometries and materials that include aluminum and Carbon Fibre Reinforced Polymer (CFRP) using the finite element (FE) analysis. The imperfection technique called the single pert...

This work study the influence of imperfections on axially compressed stiffened-stringer cylindrical shells for different geometries and materials that include aluminum and Carbon Fibre Reinforced Polymer (CFRP) using the finite element (FE) analysis. The imperfection technique called the single perturbation load approach (SPLA) is adopted. The verification analysis was performed with two cases reported in previous studies. Conversely, the parametric investigation was conducted focusing on the stiffener flange profile that varies its thickness and width. From the verification analyses SPLA demonstrated its attractive ability for designing imperfections in axially compressed aluminum stiffened cylindrical shells with fair agreement acquires. Finally, several design guidelines have been highlighted according to the parametric study and further deduced as imperfection sensitivity, buckling and post-buckling behaviour together with its collapse load and knockdown factor (KDF) of stringer stiffened cylindrical shells under axial compression primarily depend on the properties of shell and stiffeners themselves. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
