Cellular structures consist of foams, honeycombs, and lattices. Lattices have many
outstanding properties over foams and honeycombs, such as lightweight, high strength …

Mechanical metamaterials are man-made structures with counterintuitive mechanical
properties that originate in the geometry of their unit cell instead of the properties of each …

In lightweight engineering, there is a constant quest for low‐density materials featuring high
mass‐specific stiffness and strength. Additively‐manufactured metamaterials are particularly …

A wide variety of high-performance applications require materials for which shape control is
maintained under substantial stress, and that have minimal density. Bio-inspired hexagonal …

ABSTRACT A lattice structure is a space-filling unit cell that can be tessellated along any
axis with no gaps between cells. These structures are an emerging solution to weight …

A novel family of smooth-shell structures is introduced as mechanical metamaterials of
exceptional specific energy absorption capacity. The proposed shell structures respect all …

Shell-lattices consist of a single, periodic, non-intersecting shell of uniform wall thickness
that separates two intertwined void phases. To obtain a comprehensive overview on their …

This study is focused on the low-velocity impact response of 3D plate-lattices fabricated via
stereolithography additive manufacturing (AM). Elementary (SC, BCC and FCC) and hybrid …

Lightweight materials that are simultaneously strong and stiff are desirable for a range of
applications from transportation to energy storage to defense. Micro-and nanolattices …

Recent advances in additive manufacturing make it possible to fabricate periodic lattice
structures with complex configurations. However, a proper design strategy to achieve lattice …
