Elasticity Solutions for a Sandwich Orthotropic Cylindrical Shell Under External/Internal Pressure, and Axial Load

The elasticity solution is constructed for a cylindrical sandwich shell under external and/or internal pressure and for the same shell under axial load. The solution is an extension of the one for a homogeneous, monolithic shell and is provided in closed form. All three phases, i.e., the two face-sheets and the core are assumed to be orthotropic. Moreover, there are no restrictions as far as the individual thicknesses of the face-sheets and the sandwich construction may even be asymmetric. These solutions can be used as benchmarks for assessing the performance of various sandwich shell theories. Illustrative results are provided in comparison to the sandwich shell theory.
