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 …

Designing and printing metamaterials with customizable architectures enables the
realization of unprecedented mechanical behaviors that transcend those of their constituent …

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

Since the beginning of the industrial age, material performance and design have been in the

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

The local and overall responses of nonlinear composites are classically investigated by the
Finite Element Method. We propose an alternate method based on Fourier series which …

The effective mechanical properties of the octet-truss lattice structured material have been
investigated both experimentally and theoretically. Analytical and FE calculations of the …

This study reviews several problems which are specific of composites with periodic
