Abstract: This paper focuses on the study of the buckling characteristics and development of design aids for finding the lowest buckling load of cylindrical shell panels under uniform in-plane load employing finite element method. Four different types of widely used support conditions, such as simply supported (SSSS), clamped (CCCC), clamped-free-clamped-free (CFCF) and cantilever (CFFF) are considered. The various parameters such as aspect ratio, thickness ratio, shallowness ratio and boundary condition of the cylindrical panel are taken for the parametric study in this research. The parametric study shows that the above parameters influence the critical buckling loads of these panels significantly. The design charts are suggested for the cylindrical panels of commonly adopted dimensions and any isotropic material under uniform in-plane load, which would greatly benefit the designers for obtaining the critical buckling load directly from these charts during the preliminary design of these panels without using any cumbersome computer code/software.

Keywords: critical buckling load; cylindrical panel; finite element method; FEM; design charts; uniform in-plane load; aspect ratio; thickness ratio; shallowness ratio.
