Architected materials that consist of periodic arrangements of nodes and struts are lightweight and can exhibit combinations of properties (such as negative Poisson ratios) that do not occur in conventional solids. Architected materials reported previously are usually constructed from identical ‘unit cells’ arranged so that they all have the same orientation. As a result, when loaded beyond the yield point, localized bands of high stress emerge, causing catastrophic collapse of the mechanical… 

Mechanical behaviour of additively manufactured Ti6Al4V meta-crystals containing multi-scale hierarchical lattice structures

The mimicry of crystalline microstructure at meso-scale creates a new class of architected materials, termed meta-crystals, and offers effective ways to significantly improve the toughness and

Tailoring 3D Buckling and Post Contact in Microlattice Metamaterials

Mechanical metamaterials have been established as the paragons of enhanced mechanical performance, due to their properties inherited by their architected microstructure. The rapid progress in

The Twisting of Dome‐Like Metamaterial from Brittle to Ductile

Architected materials can exhibit mechanical properties that do not occur with ordinary solids. By integrating hierarchy and size effects, microarchitected metamaterials fabricated by two‐photon

Bioinspired structural materials.

TLDR
The common design motifs of a range of natural structural materials are reviewed, and the difficulties associated with the design and fabrication of synthetic structures that mimic the structural and mechanical characteristics of their natural counterparts are discussed.

Inverse Temperature Dependence of Toughness in an Ultrafine Grain-Structure Steel

TLDR
An inverse temperature dependence of toughness in an ultrahigh-strength bcc steel with an ultrafine elongated ferrite grain structure that was processed by a thermomechanical treatment without the addition of a large amount of an alloying element is observed.
