Oznake: tridimenzionalne avksetične strukture;kiralne strukture;negativno Poissonovo število;nestabilnost;three-dimensional auxetics;chiral;negative Poisson’s ratio;instability;
Auxetic materials and structures have a negative Poisson’s ratio (PR), which means that they expand under a longitudinal tensile loading and shrink under compressive load. This property gives them an increased shear resistance, damping and energy absorption capabilities. Chiral geometries are among ...

This study proposes, validates, and optimizes an innovative recoverable composite energy absorber based on a foam-filled hexachiral auxetic architecture made of a visco-hyperelastic polymer. The absorber combined a 3D- printed hexachiral frame made of thermoplastic polyurethane reinforced by waste t ...
