| Nonlinear buckling problems of hybrid thin-walled C-columns in the elastic range are discussed. A multimodal approach using Koiter’s approximation theory (SAM) was assumed to investigate an effect of different buckling modes on the ultimate load-carrying capacity. All columns were made of two layers of isotropic materials characterised by various mechanical properties and were simple supported at the ends. The results attained were verified with the finite element method (FEM). The boundary conditions applied in the FEM allowed us to confirm the eigen-solutions obtained within Koiter’s theory with very high accuracy. Nonlinear problem was solved using the Riks algorithm, which allows for investigating unsteady paths. The results for the ultimate load-carrying capacity obtained within the FEM are higher than those attained with Koiter’s approximation method, but the leap takes place on the identical equilibrium path as the one determined from Koiter’s theory. |
