The antisymmetrical laminated cylindrical shell is a multilayer composite structure composed of single-layer fiber reinforced composites bonded by fiber-opposing layer, and it is a kind of advanced composite structure with the characteristics of bistable which is not possessed by general shell structure. In this paper, based on the two-point loading method in the experimental study, taking T700/TDE-85 antisymmetrical laminated cylindrical shells as an example, the steady-state transition model
more » ... f antisymmetrical laminated cylindrical shells is established by using ABAQUS finite element software and the numerical calculation is carried out. The bistable transformation process of antisymmetric laminated cylindrical shells is simulated. The influence of ply number on the bistable behavior of the laminated structure is studied by changing the number of layers of the opposing called laminated cylindrical shells. The results show that the critical load of steady-state transition and the second steady-state residual stress increase with the increase of layer number of laminated shells, but the second steady-state crimp radius is almost unchanged.
