Mechanical Analysis of Corrugated Cardboard Subjected to Shear Stresses

Corrugated cardboard is widely used for packaging due to its sturdiness and lightweight properties. However, its ability to withstand lateral forces during handling, transportation, and storage is critical for maintaining its structural integrity. In this study, the problem of understanding and quantifying the strain experienced by corrugated cardboard boxes under shear stresses at various points in their lifecycle is addressed. Specifically, a precise methodology for testing shear stresses was developed and validated, enhancing the understanding of the material’s behaviour. Several key problems are addressed in this research, including the quantification of the amount of strain experienced by cardboard boxes from a warehouse to the final delivery, the development of a reliable testing methodology to measure shear stresses, and the understanding of the mechanical behaviour and structural integrity of corrugated cardboard under these conditions. It is anticipated that the findings will improve the design and durability of corrugated cardboard packaging, ensuring better performance during transportation and storage. This research contributes to the optimisation of logistics, the improvement of packaging quality, and the support of sustainable development by enhancing the reuse and recyclability of corrugated cardboard.
