Abstract Folded paper has a long history in origami artwork and is used by engineers to rapidly prototype designs of adaptive structures and mechanical metamaterials. However, engineers should be cautious when using paper to investigate the mechanical properties of origami structures. We show that the non-linear, pseudo-plastic behaviour of paper folds complicates the modelling of the mechanical properties of an origami structure. However, this pseudo-plastic behaviour could also present a new design space to tailor the mechanical properties of origami by controlling the rest angles of the folds.

折纸的力学：一个警示故事

摘要 折叠纸在折纸艺术中有着悠久的历史，工程师们使用它来快速制作自适应结构和机械超材料的原型设计。但是，工程师在使用纸张研究折纸结构的机械性能时应谨慎。我们表明，折纸的非线性、假塑性行为使折纸结构的机械性能建模复杂化。然而，这种假塑性行为也可以提供一个新的设计空间，通过控制折叠的静止角度来定制折纸的机械性能。
