N = number of full circumferential waves in the post-buckling pattern.

ABSTRACT: A great deal of the behavior of thin-walled cylindrical shells loaded in axial compression can be explained by considering the Yoshimura buckle pattern as a three-dimensional space frame and observing the collapse of that space frame.
