| Abstract:In this study， multiple breaks and indentations of corrugated cartons were equated into one state， and corrugated cartons with different damage and indentations were subjected to empty box compressive tests. Finite element analysis was used to verify the accuracy of the model of corrugated cartons， and the experimental data and simulation data were compared and analyzed to investigate the relationship between damage diameter， indentation length and compressive strength of corrugated cartons， in order to obtain the deformation pattern of corrugated cartons and provide a basis for rapid testing when corrugated cartons were recycled. The results showed that different damage diameters and indentation lengths had different effects on the compressive strength of corrugated cartons. When the damage diameter was greater than 110 mm or the indentation length was greater than 100 mm， the compressive strength of corrugated cartons was less than 90% of the initial compressive strength. When the diameter of the damage was less than 110 mm or the length of the indentation was less than 100 mm， the compressive strength of the corrugated cartons was not significantly affected. It could be reused by repairing the corrugated cartons to cover up the damage or indentation. |
