Abstract

Abstract : A new method to enhance the compressive strength of corrugated cartons is proposed in this study. The work aims to carry out compression tests on the corrugated carton to analyze the deformation and compressive capacity of the carton under the indentation condition of different shapes. First, compression tests are carried out on nonindentation cartons, one‐line indentation cartons, unclosed rhombus indentation cartons, rhombus indentation cartons, and cross‐indentation cartons to record their maximum compressive force. Second, by comparing the deformation of different cartons, it is found that rhombus indentation and cross‐indentation have the greatest influence on the compressive strength of cartons. Rhombus indentation will enhance the compressive strength of the carton, while cross‐indentation will reduce it. Third, ANSYS Workbench is used to analyze the buckling of cartons, and the maximum compressive force of nonindentation cartons and rhombus indentation cartons is obtained. Finally, through the comparison of the finite element method and experiments, it is concluded that rhombus indentation can improve the compressive strength of cartons, which is of great significance to the industrial production of cartons. Abstract : A new method to enhance the compressive strength of corrugated cartons is proposed without increasing the extra cost. The finite element buckling analysis is proposed to study the compressive strength of corrugated cartons. Experimental study on the effect of different indentation shapes on the compressive strength of corrugated cartons.
