Corrugated cardboard presents small geometries that make unfeasible the use of detailed three-dimensional numerical models, though homogenization approaches can be used to define equivalent homogenous plate models at a macro-mechanical scale. In this paper, we performed a finite element analysis of a well-known chair design, originally made of honeycomb cardboard, but replacing this material with single- and multiple-wall corrugated cardboard. We compared the deflections obtained under some load cases defined by he European Standards EN 1728 and EN 12520 for seating designs, with those obtained for another commercial chair design, originally made of heavy-duty triple-wall corrugated cardboard, finding comparable values. We also analysed optimized versions of both chairs, achieving lower deformations. In this way, we could find for each case the material settings with the better resistance-to-cost ratio, thus proving the utility of homogenization techniques on corrugated cardboard furniture design, as an aid to choose the most appropriate material settings.

瓦楞纸板具有较小的几何形状，因此无法使用详细的三维数值模型，尽管均质化方法可用于在宏观机械规模上定义等效的均质板模型。在本文中，我们对一个著名的椅子设计进行了有限元分析，该椅子最初是用蜂窝纸板制成的，但是用单壁和多层瓦楞纸板代替了这种材料。我们比较了欧洲标准EN  1728和EN定义的某些载荷情况下获得的挠度 12520用于座椅设计，以及用于另一种商业椅子设计的座椅，最初由重型三层瓦楞纸板制成，具有可比的价值。我们还分析了两把椅子的优化版本，以减少变形。这样，我们可以为每种情况找到具有更好的抗成本比的材料设置，从而证明了均质化技术在瓦楞纸板家具设计中的实用性，有助于选择最合适的材料设置。
