Abstract

Composite grid structures are widely used in aerospace, transportation, and construction industries. This study intends to find the optimum stacking sequence and pattern composition of the laminated grid plates subjected to uniaxial or shear buckling loads. The square and rectangular laminated grids considered were composed of four different grid patterns with equal weight and thickness. The Classical Laminated Plate Theory along with Ritz Method were used to obtain the elastic buckling loads. The grid pattern and orientation of each layer were optimized to increase the capacity of the laminated grids to handle buckling loads. Unlike previous studies, non-uniform stacking sequence was considered to further enhance the properties of the laminated grids under various boundary conditions.
