这是本文三部曲中的第三部分，研究了如何利用加法制造来促进结构分析中的基本原理的引入。每张纸都使用3D打印和简单但不平凡的细长几何形式，为弯曲起主导作用的结构行为提供了动手的方面。第一部分涉及线性结构分析(Virgin，2017)，第二部分扩展到动力学和振动(Virgin，2017)。本文主要研究细长结构，其中轴向压缩载荷是新的组成部分，因此屈曲成为一个中心问题。这与前两篇论文既有相似之处，也有不同之处，但在所有情况下，相对高精度的3D打印所起的作用都为多才多艺和有效的插图打开了大门，并促进了对结构现象的更深入理解。
This is the third part in a trilogy of papers examining ways in which additive manufacturing can be used to facilitate the introduction of basic principles in structural analysis. Each paper uses 3D-printing and simple, but non-trivial, slender geometric forms, to provide a hands-on aspect to structural behavior in which flexure plays a dominant role. The first part dealt with linear structural analysis (Virgin, 2017), extended to dynamics and vibration in the second part (Virgin, 2017). The current paper focuses on slender structures in which compressive axial loading is the new ingredient and hence buckling becomes a central issue. This has similarities and differences with the two previous papers, but in all instances the role played by relatively high-precision 3D-printing opens the door to versatile and effective illustration, and the development of a deeper appreciation of structural phenomena.
