POSSIBLE FORMS OF AXISYMMETRICAL LOSS OF STABILITY IN CYLINDRICAL SHELLS UNDER AXIAL COMPRESSION,
Abstract
Experiments show that axisymmetric buckling of cylindrical shells compressed in the axial direction may be symmetric and antisymmetric with respect to the midsection of the shell. The experimental values of critical stresses for short cylindrical shells are only a fraction of the upper critical stress. It is theoretically shown that antisymmetric loss of stability is the only form possible for extremely short shells, the shell (or more precisely the ring) being turned inside out. An expression is derived for the relative longitudinal extension of the shell fibers at a given distance from the midsection of the ring. For sufficiently short shells, buckling begins immediately after application of the load with a resultant loss of stability due to development of plastic deformations or the axisymmetric (zonal) form of buckling is replaced by the nonaxisymmetric (tesseral) form.
