瓦楞纸板具有带有小凹槽的波形芯，妨碍使用整个结构的详细数值模型。文献中的许多均质化方法通过在宏观机械尺度上定义具有相同机械行为的等效均质板来克服这一缺点。然而，很少有均质化工作考虑完整的结构，主要集中在梁或板。这项研究首次探讨了均质化方法在大型结构中的应用，以帮助其设计过程。我们还考虑了三壁板，而不是文献中常见的单壁和双壁配置。为此，我们采用 Talbi 和 Duong 提出的均质化方法来分析由三层瓦楞纸板制成的薄壁凳子。通过采用渐进式设计流程，我们通过去除应力较低的材料区域来进行高效的凳子设计，与初始设计相比，材料减少了 35%，垂直变形减少了 35%，应力减少了 66%。与其他瓦楞纸板凳不同，这种设计仅包含一个折叠件而不是三个，从而节省了存储空间。这些结果证明了均质化技术在瓦楞纸板整体结构设计过程中的辅助作用。进一步的研究将考虑屈曲分析。
Corrugated cardboard has waved cores with small flutes that prevent the use of detailed numerical models of whole structures. Many homogenization methods in the literature overcome this drawback by defining equivalent homogeneous plates with the same mechanical behaviour at a macro-mechanical scale. However, few homogenization works have considered complete structures, focusing mainly on beams or plates. For the first time, this study explores the application of homogenization approaches to larger structures as an aid in their design process. We also considered triple-wall boards rather than single- and double-wall configurations commonly addressed in the literature. To this end, we adapted the homogenization methods proposed by Talbi and Duong to analyze thin-walled stools made of triple-wall corrugated cardboard. Using a progressive design process, we performed an efficient stool design by removing material zones with lower stresses, with 35% less material, 35% lower vertical deflections, and 66% lower stresses than the initial design. Unlike other corrugated cardboard stools, this design comprises just one folded piece instead of three, thus saving storage space. These results demonstrate the utility of homogenization techniques as an aid in the design process of whole structures made of corrugated cardboard. Further research will consider buckling analysis.
