| Abstract |
The mechanical properties of metamaterials with a cellular chiral internal structure were
experimentally studied during normal penetration by a rigid spherical striker. The metamaterial samples were 3D printed from TPU 95A plastic (thermoplastic polyurethane). They had auxetic and nonauxetic chiral structures of cells in the form of concave and convex hexagons, respectively. The results
of the experiments on sample penetration, conducted for two temperature and two speed modes, are
presented. The relative loss of kinetic energy of the striker during penetration of auxetic samples was
significantly higher than that of non-auxetic ones. It was found that for the studied types of flexible
metamaterials, the resistance to striker penetration increases with increasing temperature in the considered temperature range. The dependence of the striker deviation on exit from the flexible sample on
the type of chirality of the structure being penetrated was established. |
