BUCKLING OF A MULTI-ANNULAR ANNULUS

This contribution presents a solution for a critical buckling force in a thin two-ring annulus. Because of the changes in the properties of each particular ring, the problem belongs to a group of plane elements with so-called cylindrical orthotropy. The purpose of this study is t o determine the critical radial compressive load depending on the chan ges in bending rigidity of each particular ring, changes of boundary c onditions and the manner of edge loading in this kind of annulus.
