EN: The problem of buckling of closed elastic shallow circular thin-walled cones
under external pressure is a classic problem of shells theory. Both geometrically
linear and nonlinear solutions were provided for this problem. It’s well known fact,
that a sensitivity of critical and limit pressures to the initial imperfections of the
middle surface of shallow conical shells shape is relatively small. The question of
influence of material’s orthotropy on the buckling load of shallow conical shells
remains insufficiently studied.
