Horton, W. H. and Durham, S. C., “The Effect of Restricting Buckle Depth in Circular Cylindrical Shells Repeatedly Compressed to the Buckling Limit,” SUDAER No. 174, Stanford University, November 1963
The cylindrical shell has a mandrel inside that prevents the buckles from growing without limit.
The buckling load of this type of shell under uniform axial compression is extremely sensitive to initial geometric imperfections, as is demonstrated in the next several slides.
