Architected materials for enhanced energy absorption
First Claim
1. A three-dimensional lattice architecture with a thickness hierarchy, comprising:
- a first surface and a second surface separated from each other with a distance therebetween defining a thickness of the three-dimensional lattice architecture;
a plurality of angled struts extending along a plurality of directions between the first surface and the second surface; and
a plurality of nodes connecting the plurality of angled struts with one another forming a plurality of unit cells;
wherein at least a portion of the plurality of angled struts are internally terminated along the thickness direction of the lattice architecture short of the second surface of the lattice architecture, an end of each internally terminated angled struts extending towards the second surface being a non-contacting end inside the lattice architecture.

Abstract
A three-dimensional lattice architecture with a thickness hierarchy includes a first surface and a second surface separated from each other with a distance therebetween defining a thickness of the three-dimensional lattice architecture; a plurality of angled struts extending along a plurality of directions between the first surface and the second surface; a plurality of nodes connecting the plurality of angled struts with one another forming a plurality of unit cells. At least a portion of the plurality of angled struts are internally terminated along the thickness direction of the lattice structure and providing a plurality of internal degrees of freedom towards the first or second surface of the lattice architecture.
