Abstract Cellular solids, as a class of materials, are known for a high strength to weight ratio. Their design into non-stochastic configurations is known to be beneficial for the tailor and control of their mechanical properties. The current developments on additive manufacturing allow a successful route to manufacture these scaffolds and gives a novel freedom in their design process. This study explores the deformation behavior of axisymmetric non-stochastic cellular solids, allowing the understanding of the mechanisms that enhance their mechanical properties relatively to regular extruded lattices. It is shown that axisymmetric samples display a circumferential deformation effect that distributed loads along the volume of the material. This effect, however, is more prominent in axisymmetric samples with auxetic behavior. The coupling of circumferential deformation and the dynamic density changes in auxetic samples generate an overall increase in modulus, collapse stress and energy absorption.

使用轴对称配置增强多孔固体的机械性能

摘要 多孔固体作为一类材料，以高强度重量比而著称。众所周知，将它们设计为非随机配置有利于其机械性能的定制和控制。增材制造的当前发展为制造这些脚手架提供了一条成功的途径，并为其设计过程提供了新的自由度。本研究探讨了轴对称非随机细胞固体的变形行为，从而有助于了解相对于规则挤压晶格增强其机械性能的机制。结果表明，轴对称样品显示出沿材料体积分布载荷的周向变形效应。然而，这种效应在具有拉胀行为的轴对称样品中更为突出。
