The primary benefit of metamaterials is that their physical and mechanical properties can be controlled by changing the structure geometry. Numerical analysis tools used in this work offer a few advantages over full-scale testing, consisting of an au

This paper studies a mechanical metamaterial with tetrachiral topology by mathematical modeling. Chirality is the property of an object that makes the object distinguishable from its mirror image; chirality can be left- or right-handed. The mechanica

Characterization of a chiral metamaterial depending on the type of connection between unit cells

Autor: Linar Akhmetshin, Igor Smolin

Publikováno v: Proceedings of the Institution of mechanical engineers, Part C: Journal of mechanical engineering science. 2022. Vol. 236, № 19. P. 10214-10220

The main focus in the development of metamaterials is on the design of multiscale structures, rather than on the chemical composition and properties of the base materials. In this work, a mechanical metamaterial is studied by mathematical modeling an
