Pattern transformation induced waisted post-buckling of perforated cylindrical shells

•Waisted post-buckling pattern transformation is concluded for clamped cellular cylindrical shells.•Shell theory can be used to analyze negative Poisson's ratio formed by waisted post-buckling.•Load-carrying capacities of cellular cylindrical shells undergo sudden drop but recover subsequently.•Waisted post-buckling behavior could appear for thin-walled shell without external support.•Waisted post-buckling patterns may be found on other curved structures such as cylindrical panels.
