Abstract:Stiffened panels are used to reduce the displacement by loading. This study deals with the numerical simulation of stiffened panels in which the stiffeners are integrated to the panel. The panel is subjected to compressive load along the stiffener axis. This induces buckling stress in the structure. In this study, a Tee shaped stiffener is used for analysis. The focus of the study is to investigate the deformation as well as structural integrity of an integrated stiffened panel by performing buckling analysis and all the comparisons are made with conventional stiffened panel using ANSYS software. The simulation reveals that the integrated stiffened panel gives an improved performance than the conventional design. The integrated stiffened panel shows around 1.2% higher strain rate, stress capacity higher by nearly 4.864% and around 20.25% deformation resistance variation compared to the conventional panel. Therefore, the integrated stiffened panel is found to be an acceptable alternative to the conventional stiffened panel design.
