【Abstract】 The stability of a large opening composites conic shell stiffened with nettings under axial compression, external pressure and their combination is calculated in this paper. the critical load of the large opening conic shell with different angers of lamination and under different loading is obtanined, the calculated value of the conic shell under axial compression is compared with the experimental results.更多还原
