Buckling Analysis of Stiffened Panel for Aircraft Fuselage
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2018, Vol 8, Issue 1
Abstract
In the present work, structural analysis of stiffened panel for aircraft fuselage is performed for pure composites and composite plates with isogrid and orthogrid using FEM. In the bulking analysis of the panel, the static analysis is carried out under the specified loading and boundary conditions and results are extended to the buckling analysis. In the buckling analysis of stiffened panel, the mode shapes are extracted and frequencies are tabulated. The material selected for the analysis is carbon fiber, carbon fabric epoxy composite by precision contact lay-up. The fiber orientation for the isogrid structure is 600/300 and for the orthogrid, the fiber orientation is 00/900. The analysis shows that the orthogrid structure is better than the other panels. The inplane load bearing capacity of the orthogrid structured panel is more than the isogrid panel structure. The weight of the orthogrid structured panel is less than the isogrid stiffened panel.
