Effect of edge conditions on buckling of stiffened and framed shells

"October 20, 1967.""A series of stiffened shells made of plastic were tested to verify the theoretical equations for the effect of edge conditions on the buckling of stiffened and framed shells. The theory was developed by calculating the deflections during loading and prior to buckling, and by using a large deflection stability approach. The agreement between the test results and the theory was good. Tests also confirmed that the edges could be stiffened and relatively high buckling loads could be obtained by increasing the meridional curvature near the edge of the shell."--Summary
