INEXTENSIONAL BUCKLING CONFIGURATION OF CONICAL SHELLS.

Abstract

Relations describing the geometrical forms taken by a thin conical shell when it shortens under axial compressions by pure folding are presented. These forms are convex polyhedral surfaces characterized by two distinct sets of triangular planes, one rotated toward (called the (+) surface) and the other away from (called the (-) surface) the generatrix of the underformed cone. The number of circumferential waves in each row remains constant along the length of the shell, with the size varying according to the cone diameter. The (+) and (-) surface have distinct aspect ratios, the (-) surface being always the more slender in the circumferential direction. The relations are valid for all degrees of axial shortening including that corresponding to total collapse. Collapse patterns obtained from experiments are shown to agree well with those constructed from the theory. (Author)
