Shell Parameter Influence on the Failure Mode of Side - On Air Blast Loaded Cylinders

Abstract

The purpose of this investigation is to determine the influence of the shell size parameters, length-to-diameter ratio and diameter-to-thickness ratio, on the failure mode of cylinders under side-on air blast loading. These failure modes are: (1) hinge collapse, (2) wave buckling, and (3) combination. The results of this study show that the diameter-to-thickness, (D/h), ratio dominates the shell behavior and that for values of D/h below 110, hinge collapse seems to be dominant; between 110 and 450, combination failure seems to be dominant; above 450, wave buckling seems to be dominant.
