论文摘要
拓扑互锁的物质系统是单位元素的二维组件，而无需拆卸整个系统，就无法从组件中删除元素。因此，此类瓷砖组件能够携带横向机械载荷。 Archimedean和Laves Tilings作为材料系统架构的模板进行了研究。在点载荷下证明，该体系结构显着影响力反射响应。刚度，承载能力和韧性的差异至少有三个因素，其性能最差的系统性能最差。在所有体系结构中，都发现强度和韧性与僵硬和线性相关。研究了特征参数及其与机械行为的关系的结构。结果表明，组装中最小的瓷砖面积的度量为机械行为提供了最佳预测指标。在组件中存在小瓷砖的情况下，接触力网络结构的发育良好，并且内部负载路径通过组件的这些最僵硬的组件引导。
Topologically interlocked material systems are two-dimensional assemblies of unit elements from which no element can be removed from the assembly without disassembly of the entire system. Consequently, such tile assemblies are able to carry transverse mechanical loads. Archimedean and Laves tilings are investigated as templates for the material system architecture. It is demonstrated under point loads that the architecture significantly affects the force-deflection response. Stiffness, load carrying capacity and toughness varied by a factor of at least three from the system with the poorest performance to the system with the best performance. Across all architectures stiffness, strength and toughness are found to be strongly and linearly correlated. Architecture characterizing parameters and their relationship to the mechanical behavior are investigated. It is shown that the measure of the smallest tile area in an assembly provides the best predictor of mechanical behavior. With small tiles present in the assembly the contact force network structure is well developed and the internal load path is channeled through these stiffest components of the assembly.
