Abstract:Taking the hyperbolic doublycurved shells structure composite as the research object, the thermal buckling behavior of the composite laminated hyperbolic doublycurved shells structure under the temperature field is studied by using the finite element BlockLanczos research analysis method, and the influences of the laminated thickness, boundary conditions, fiber direction of the composite laminated hyperbolic doublycurved shells on the critical buckling temperature are studied. The results show that the critical buckling temperature of the hyperbolic doublycurved shells of composite laminates is closely related to the boundary conditions, ply thickness and fiber direction and has a certain regular distribution under uniform temperature field. Through the thermal buckling analysis of composite hyperbolic doublycurved shells structure in this paper, an effective analysis and modeling method is provided for structural design and practical application of composite Materials
