The mechanical properties of ice X with particular emphasis on its auxetic potential

Cancellation of Auxetic Properties in F.C.C. Hard Sphere Crystals by Hybrid Layer-Channel Nanoinclusions Filled by Hard Spheres of Another Diameter

“…Novel structures [26][27][28][29][30][31][32][33][34], nanostructures [35,36], and models [37][38][39][40][41][42][43][44], real materials (e.g., polymers [45,46], composites [47], or foams [48,49]), and metamaterials [50,51] with auxetic properties have been designed and reported. These advances in real metamaterials would not have been possible without more basic research [52][53][54], analysis [55][56][57][58][59], and optimization [60,61] of auxetic models on various levels. This effort is motivated by the extraordinary, counterintuitive elastic properties and potential applications of auxetics [62][63][64][65][66][67][68].…”

The Mechanical Properties of CO2‐II with Particular Emphasis on Its Auxetic Potential

“…Thus, in the case of this study, the auxetic behavior of CO 2 ‐II was rationalized by studying the changes in the Raman and infrared spectra under different pressure conditions. A similar approach was taken in previous work, [ 63,64 ] where spectroscopic measurements were utilized to consolidate the proposed deformation mechanism determined through the nanoscale deformation of the system.…”

Boron Arsenate Scaled‐Up: An Enhanced Nano‐Mimicking Mechanical Metamaterial

“…More recent work by Grima-Cornish et al [53] also looked at the mechanical properties of BAsO 4 over a range of hydrostatic pressure and examined how pressure affects its mechanical properties. In this study, which needs to be placed in the context of other works which look at the effect of pressure on mechanical properties, [16,18,[57][58][59][60][61][62][63][64][65][66] it was shown that when BAsO 4 is subjected to a hydrostatic pressure together with an additional load in the [1] direction, the material manifests a negative Poisson's ratio over an extensive pressure range up to c. 30 GPa. This was found to be caused by two mechanisms, both of which lead to auxeticity, namely the expected one, describable in terms of rotations of the projected squares in the (001) plane and which is the result of rotations and reorientation of the tetrahedra, and a second mechanism, which is more predominant at higher pressures and involves deformation of the tetrahedra themselves which become flattered.…”
