Abstract : The lower critical load of a thin, circular, right conic shell under conditions of uniform longitudinal compression is determined. It is assumed that the postcritical condition is reached mainly via geometrical bending. In view of this, the surface which is isometric to the undeformed middle surface is studied. The isometric surface consists of 2 n cylindrical surfaces, the generatrices of which are perpendicular to n planes of symmetry; their number is equal to the number of surfaces originating at the moment of stability loss. For one cylindrical part the energy of deformation is also calculated. The effect of conicity on the lower critical load is investigated. (Author)
