在最近的一次交流[1]中，我们提出了一种新的材料架构，该架构基于相同互锁元素的规则组装。元素的堆积拓扑结构防止每个单独的“构建块”被其紧邻的元素破坏。我们相信，这种互锁结构的理论可能性为创造具有高抗冲击性的坚固而柔韧的复合材料开辟了新的方向。虽然互锁元件形成可以提供复合材料的结构完整性的骨架结构，但是可以选择第二相以满足特定的功能要求，例如关于导电性或导热性、声音衰减等。由于组件的性质由它们的拓扑结构确定，而不是由“构建块”的尺寸确定，提出的拓扑驱动材料设计原理也可用于大型结构。本文研究了基于拓扑互锁原理设计的材料的一些力学性能。
In a recent communication [1] we proposed a new material architecture that is based on regular assemblies of identical interlocked elements. The topology of packing of the elements prevents each individual ‘building block’ from breaking out by its immediate neighbours. We believe that the theoretical possibility of such interlocked structures opens up a new direction for creating strong and flexible composite materials with high impact resistance. While the interlocked elements form a skeleton structure that can provide structural integrity of the composite, a second phase can be selected to satisfy specified functional requirements, e.g. with regard to electrical or thermal conductivity, sound attenuation, etc. Since the properties of the assemblies are determined by their topology, rather than by the size of the ‘building blocks’, the topologically motivated materials design principle proposed can be used in large scale structures, as well. In the present paper, we investigate some mechanical properties of materials whose design is based on the topological interlocking principle.
