Mechanical metamaterials can be defined as a class of architected materials that exhibit
unprecedented mechanical properties derived from designed artificial architectures rather …

Abstract In 1903, Alexander Graham Bell developed a design principle to generate
lightweight, mechanically robust lattice structures based on triangular cells; this has since …

After a decade of periodic truss-, plate-, and shell-based architectures having dominated the
design of metamaterials, we introduce the non-periodic class of spinodoid topologies …

Structural hierarchy can enhance the mechanical behavior of materials and systems. This is
exemplified by the fracture toughness of nacre or enamel in nature and by human-made …

We present a two-scale topology optimization framework for the design of macroscopic
bodies with an optimized elastic response, which is achieved by means of a spatially-variant …

Though beam-based lattices have dominated mechanical metamaterials for the past two
decades, low structural efficiency limits their performance to fractions of the Hashin …

A successful working model for nanoporosity evolution during dealloying was introduced 15
years ago. Since that time, the field has rapidly expanded, with research groups from across …

Spatial confinement in nanoporous media affects the structure, thermodynamics and mobility
of molecular soft matter often markedly. This article reviews thermodynamic equilibrium …

The understanding and management of strain is of fundamental importance in the design
and implementation of materials. The strain properties of nanocrystalline materials are …

Atomic-level modeling of materials provides fundamental insights into phase stability,
structure and properties of crystalline defects, and to physical mechanisms of many …
