The buckling of a sandwich cylindrical shell under uniform external hydrostatic pressure is studied in three ways. The simplifying assumption of a long shell is made (or, equivalently, 'ring' assumption), in which the buckling modes are assumed to be two-dimensional, i.e. no axial component of the d
