This paper proposes a novel approach to represent the geometry of the corrugated board profile during compression using graphs. Graphs are lighter than images, and the computational time of compression analysis is then significantly reduced compared to using the original image data for the same analysis. The main goal of using such graphs is to gain more knowledge about the mechanical behavior of corrugated boards under compression compared to the current load-deformation curve approach. A node tracking algorithm is applied to characterize the different phases occurring during the compression test in order to predict physical phenomena, including buckling and contact. The main results show that analyzing the nodes provides significant insights into the compression phases, which has not been achieved in the current state of the art. The authors believe that the objective of this research is crucial to better understanding the physics of corrugated boards under compression, and it can also be extended to other engineering structures.
本文提出了一种新颖的方法，利用图形来表示瓦楞纸板在压缩过程中的轮廓几何形状。图形比图像更轻量级，因此与使用原始图像数据进行相同分析相比，压缩分析的计算时间显著减少。使用此类图形的主要目的是，相较于当前的载荷-变形曲线方法，能够获取更多关于瓦楞纸板在压缩状态下力学行为的知识。应用节点跟踪算法来表征压缩测试过程中出现的不同阶段，以便预测包括屈曲和接触在内的物理现象。主要结果表明，分析节点能为压缩阶段提供重要见解，这是当前技术水平尚未实现的。作者认为，本研究的目标对于更好地理解瓦楞纸板在压缩状态下的物理特性至关重要，并且该方法还可扩展到其他工程结构。
