| The objective of this work is to predict the plate elastic buckling includes critical buckling load and corresponding buckling mode for stiffened and unstiffened plate under in-plane loading. The numerical study has been achieved by employing the FEM (ANSYS package ver.11) using a shell element of eight nodes with five DOF at each node as a discretization element such that the equation of elastic stability with isotropic material properties has been taken into consideration studies. The study of aluminum alloy 6063-O plates subjected to in-plane loading showing the effect of stiffened plates, stepped thickness, and changing of applied loading. It has been found that buckling strength increases when plate width (b) increase for stiffened and unstiffened plate, also critical buckling load has high values for biaxial load than uniaxial for plates with the same specification. Also, an experimental test has been performed on different cases which exhibit a good verification of results. | ||
