It is difficult to precisely predict the ultimate buckling strength for the complex buckling mechanism of corrugated board. Nonlinear buckling analysis of corrugated board column was carried out by using nonlinear finite element method, the ultimate carrying capacity was calculated, and the main factors influencing carrying capacity of the corrugated board column was analyzed. The results showed that it is feasible and valuable to carried out buckling analysis of corrugated board structure using nonlinear finite element method; the result can be reference for structure design of corrugated paper package.
