论文摘要
本文介绍了链晶格，这是一种层次桁架结构，包括两个互穿晶格。一个晶格会坚固材料并防止灾难性的局部破坏，而另一个晶格则用作多孔矩阵，在拉伸载荷期间吸收能量。链晶格可以适合增材制造，并且可以将通常易碎且对缺陷敏感的3D打印材料转化为耐受耐受的材料。计算预测，陶瓷链晶格可以具有比完全致密的同类物的特定能量吸收数量级。
This paper introduces the chain lattice, a hierarchical truss structure comprising two interpenetrating lattices. One lattice toughens the material and prevents catastrophic localized failure while the other lattice serves as a porous matrix that densifies to absorb energy during tensile loading. Chain lattices are amenable to additive manufacturing and can transform 3D-printable materials that are normally brittle and flaw-sensitive into damage-tolerant materials. Calculations predict ceramic chain lattices can have a specific energy absorption several orders of magnitude greater than that of their fully dense counterparts.
