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 …

As one of the most important additive manufacturing (AM) techniques, laser metal deposition
(LMD) has been extensively studied specially during the last few years. Similar to other AM …

Auxetic materials and structures have many potential applications due to their counter-
intuitive deformation behavior and desirable mechanical properties. However, auxetic …

Here, we present the in-plane energy absorption characteristics of modified re-entrant
auxetic honeycombs realized via fused filament fabrication in conjunction with parametric …

Novel 3D printed square auxetic tubular lattice (SATL) structures were designed, fabricated
and investigated. Their mechanical properties were examined by the finite element method …

In the past decades, auxetic metamaterials have attracted extensive attention due to their
desirable properties. In order to further improve the energy absorption properties of auxetic …

Artificially-structured materials with negative Poisson's ratio, also known as auxetics, have
been the focus of numerous studies over the past few decades. In this paper, using a group …

Ceramic aerogels are promising lightweight and high-efficient thermal insulators for
applications in buildings, industry, and aerospace vehicles but are usually limited by their …

Mechanical metamaterials have been designed to achieve custom Poisson's ratios via the
deformation of their microarchitecture. These designs, however, have yet to achieve the …

Auxetic materials have been widely studied in recent years due to their excellent mechanical
properties and special deformation modes. However, the application of auxetic materials in …
