Metamaterials are of great interest due to their unusual properties and promising practical application. In the paper, we study a mechanical metamaterial bar composed of 81 unit cells. The unit cell has the shape of a cube with the two-dimensional tetrachiral base consisting of a ring and four ribs. Elastic deformation of a metamaterial specimen is numerically modeled in uniaxial compression and tension. The influence of the varying the parameters of the unit cell on the metamaterial response is studied.
