The formation of small, flexural wrinkles in the walls of a sandwich shell under uniform radial impulse is examined. A buckling criterion based on the magnifications of initial wall imperfections is used to evaluate threshold impulses. Using a given weight of material, this criterion is used to determine the optimum ratios of the inner and outer wall thicknesses for various core thicknesses. It is shown that the optimum shell for a given weight of material and outer diameter is a single-wall shell. The loss in efficiency obtained by using typical sandwich shells is about 30 percent. These results are supported by experimental evidence.
