FREE-VIBRATION AND BUCKLING OF SYMMETRICAL CROSS-PLY RECTANGULAR LAMINATES

The method of superposition is further developed to analyze free vibration and buckling of symmetric cross-ply laminated rectangular plates. The improved plate theory developed by Mindlin is implemented. A four building block technique is employed that reduces the number of combinations of classical boundary conditions that need to be studied. Combinations of clamped and simply supported boundary conditions are investigated, Eigen-values and critical buckling loads with four-digit accuracy are obtained for plates with five distinct combinations of simply supported and clamped boundary conditions.
