Design Curves for the Buckling of Sandwich Cylinders of Finite Length Under Uniform External Lateral Pressure
Abstract
Curves and formulas are presented for the calculation of the critical external pressure of finite length, circular cylindrical shells with sandwich walls. The facings of the sandwich are equal and isotropic and their individual stiffness is not taken into account. The sandwich core is isotropic or orthotropic having natural axes in the axial, tangential, and radial directions of the cylinder. Curves are given for cylinders with sandwich walls having isotropic cores and orthotropic cores having certain relative elastic properties. If the cores are very rigid, the method yields results that are substantially those of von Mises.
