Rise of the Poisson’s Ratio in f.c.c. Hard Sphere Crystals with the Narrowest Orthogonal Nanochannels Filled by Hard Spheres of Another Diameter
Narojczyk Jakub W., Tretiakov Konstantin V., Wojciechowski Krzysztof W.
Auxetic materials, i.e. materials exhibiting negative Poisson’s ratio, stand to answer the demand for novel materials with unique and application-tailored properties. The vast range of potential applications motivates researchers to search for new materials with such properties, or to look for ...
Poisson’s Ratio of Yukawa Systems with Nanoinclusions: Nanochannel vs. Nanolayer
Tretiakov Konstantin V., Wojciechowski Krzysztof W., Narojczyk Jakub W., Pigłowski Paweł M.
The influence of periodically distributed inclusions on elastic properties of crystals in which particles interact through Yukawa potential is discussed briefly. The inclusions in the form of channels oriented along the [001]-direction and layers orthogonal to the [010]-direction are considered. ...
Smart Cellular Systems with Pressure Dependent Poisson’s Ratios
Attard Daphne, Cauchi Reuben, Gatt Ruben, Grima-Cornish James N., Grima Joseph N.
The Poisson’s ratio behaviour of cellular systems which change their internal features when subjected to pressure change to become a “re-entrant” or “non-re-entrant” honeycomb was investigated. It was shown, through finite elements simulations, that these changes in geometry permit the ...
