Abstract

The shear buckling of the Carbon Fiber Reinforced Polymer composite (CFRP) hat-stiffened panels is studied through experiment, theoretical analysis, and numerical simulation. Composite hat-stiffened panels are tested via the distributed load technique. The strain distribution of the skin of composite hat-stiffened panels is deduced based on the composite linear elasticity theory under shear load. Theoretical and semi-experiential approaches are proposed to predict the initial buckling load of hat-stiffened panels with two boundary conditions and three strip widths of skin. Finite element analysis is used to simulate shear buckling with the eigenvalue analytical method and the geometrical nonlinearity method. The analytical results and experimental results are compared. The results show that the strain distribution of skin of panels and test data are consistent, which verifies the effectiveness of strain formula of skin. Adopting theoretical and semi-experiential approaches, a relatively accurate shear buckling load can be obtained with proper boundary conditions and strip widths of the skin. The buckling load derived through the eigenvalue analytical method is higher than the experimental load. The buckling process can be simulated with appropriate initial imperfection through the geometrical nonlinearity method.
