Study on the Buckling Deformation of Orthotropic Strip

Abstract:

Because of the crystal preferential orientation, the rolled strip exhibits orthotropy. The mechanism and deformation behavior of the orthotropic strip buckling (included pre-buckling and post buckling) was studied by analytical and finite element method. Through the energy principle, the mathematical model of critical buckling was established, and the critical conditions were obtained. The generating path of post buckling was found with perturbation variational solution. At the same time, using software ANSYS to simulate the buckling deformation, then the buckling mode, the critical stress and the post-buckling path were obtained, which were in good accordance with the analytical results. It verified the accuracy of analytical results.
