Minimum-Mass Design of Filamentary Composite Panels under Combined Loads: Design Procedure Based on Simplified Buckling Equations.

Abstract

An analytical procedure is presented for designing hat-stiffened and corrugated panels made of composite material and subjected to longitudinal (in the direction of the stiffeners) compression and shear loadings. The procedure is based on nonlinear mathematical programing techniques and a simplified set of buckling equations. Design requirements considered are buckling, strength, and extensional and shear stiffness. Studies show the effects of specified thickness, variation of cross-section dimensions, stiffness requirements, local-buckling boundary conditions, and the effect of combined compression and shear loadings.
