Buckling Analysis of Stiffened Composite Panels for Different Ply Orientations

Buckling and post-buckling analysis was performed on composite stiffened panel using Abaqus/CAE to obtain the critical load and modes of failures, with different parameters like ply orientation, different composite materials, stiffeners & by changing the number of stiffeners were derived. To investigate the buckling behavior of composite curved stiffened panels, the nonlinear FE tools Abaqus/Explicit are employed. Studies were conducted using the analytical tool in order to understand the structural behavior in the post buckling range and to determine the critical parameters.
