The buckling behaviors of composite circular cylindrical shells subjected to axial compression are investigated by the analytical(Dow and Rosen) solution based on the classical orthotropic theory and the finite element analysis.
For circular cylindrical members, the buckling behaviors turn out that the shell buckling analysis have to be considered for values of the length over radius(L/R) ratio approximately lower than 5∼10.
In cases considered(L/R=5, R/t=3-100) for composite circular cylindrical shells under axial compression, the linear buckling loads for both the finite element analysis and the elasticity solution show good agreement unlike Dow and Rosen solution. From these results, we can conclude that the finite element analysis predicts the accurate critical load for values of the radius over thickness(R/t) ratio approximately between 10 and 20.
