On the numerical analysis of experimental data on the buckling of conical shells

Abstract

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.
