Abstract
In this paper, based on the mixed-type theory, a theoretical analysis is presented for buckling of laminated composite circular conical shells under external pressure. By using the potential energy variation principle the formulas for critical external pressure are obtained. Very good agreement is shown between the theoretical prediction of critical external pressure and the experimental data. Finally, the influence of some parameters on critical external pressure is numerically discussed. The results obtained in this paper are very useful in aerospace engineering design.
