摘要
This paper investigates the relationship between mechanical behaviors and the shape of corrugated fiberboard by means of buckling analysis, which is done by FEM (Finite Element Method). Firstly, after analyzing the structure of corrugated fiberboard, a single-wall corrugated fiberboard model was built. The buckling load was measured in the ideal condition by linear buckling analysis (eigenvalue buckling analysis). Subsequently, nonlinear buckling analysis based on single-wall corrugated fiberboard was performed using the results of the eigenvalue buckling analysis. Finally, a finite element 3-D model of four-layer and five-layer corrugated fiberboard was established using ANSYS parametric design language (APDL) to improve mechanical properties of corrugated fiberboard based on comparing different eigenvalue buckling loads.
