    Abstract
  • The compression properties of composite cylindrical shell under axial compression load were tested, and the failure load and the load-strain curves for composite cylindrical shell of test points were collected. The results show that the damage form of the cylindrical shell is buckling failure. A relative finite element model was established and the buckling behaviors of composite cylindrical shell were analyzed by ANSYS software. The results obtained by simulation and experiment were consistent with each other, which validate the effective model. Based on the finite element model, the influences of opening size and fiber ply angle on buckling load of the cylindrical shell with rectangular opening were analyzed. A composite cover was installed to reinforce the structure, and the strength of the reinforced cylindrical shell meets the design requirement.
