We manufactured sandwich-walled cylinders with longitudinal and circumferential corrugated cores from carbon fiber reinforced composites using a sequential hot press moulding method. As the first step for manufacturing these structures, we fabricated the integral corrugated cores using assembled steel moulds. Then a set of curved sheets was bonded to the corrugated cores to form cylindrical sandwich shells. Axial compression tests were performed on specimens with different geometries to investigate the failure behavior of these structures. For the cylindrical shells with longitudinal cores, both local buckling and face crushing were observed during the experiment with face crushing being the dominant failure mode. For the cylindrical shells with circumferential cores, local buckling was found to be the dominant failure mode. In addition, analytical models pertaining to Euler buckling, shell buckling, face crushing and local buckling failure modes were presented. The models were used to construct failure maps for different specimen geometries. Finally, energy absorption calculation showed that cylindrical shells with longitudinal cores have better energy absorption ability than that with circumferential cores.

Shell eigen buckling behaviour is investigated for combined axial and lateral pressure loading and with various end conditions. In addition to the more common pinned (P) and clamped (C) end conditions, particular emphasis is placed on shells where one or both of the ends are free (F). The physical behaviour in different geometry ranges is used to develop simple, approximate eigenvalue formulae, which are verified against the predictions of linear shell buckling theory using the method of variations. The different end conditions are treated through multipliers to the well-known pin-ended (P–P) case. It is found that, for practical geometries, P–F shells are very much weaker than C–F shells due to the lack of warping restraint. The results have application to the design of suction caisson foundations for offshore platforms.
