metadata.name: dc.description.abstract
metadata.value: In the paper, we study the mechanical behavior of a three-dimensional chiral mechanical
  metamaterial using numerical modeling. A feature of chiral structures is that during their
  uniaxial loading a twisting is observed along the loading axis. A rod of the mechanical
  metamaterial composed of 3 × 3 × 9 unit cells along the corresponding three orthogonal
  axes. The relative strain of uniaxial compression of the sample in the simulation did not
  exceed 3.3%. The simulation was performed by the finite element method in a threedimensional
  case. Original results on the dependencies of the rotation angle and the reaction
  of the rigidly fixed support of the metamaterial sample on the parameters characterizing
  the structure of the unit cell of the metamaterial are presented in this context. All the
  dependencies, except one, are nonlinear with portions of large and small changes.
