ABSTRACT
Numerical analysis of experimental research on buckling of closed shallow conical shells
under external pressure was carried out in ANSYS Inc simulation software. The obtained
experimental data was compared with calculation results for more than 100 small-sized
specimens of conical shells with a wide range of different geometry. All most important
features of carrying out physical experiments were taken into account in the simulations.
In particular, orthotropy of the shell material has been considered. The critical pressure
values can be obtained in ANSYS software for existing conical shell structures with known
geometry deviation comparing to ideal.
