Book excerpt: An experimental investigation was made to determine the axial buckling load of cylinders formed by a process of plastic expansion due to internal pressure. Test cylinders 21.6 cm in diameter, 0.330 mm thick, were formed by plastic expansion from 15.23 cm diameter commercial, welded, type 304 stainless steel tubing. Buckling loads from 50 to 71 percent of the classical value showed a definite relationship with the local decrease in curvature due to the worst imperfections. Buckling loads were substantially higher than expected in relation to the amplitude of their geometric imperfections. The results indicate that the process of plastic expansion may provide a means of producing certain types of cylinders of unusually high buckling load at low cost.
