Testing the metamaterial blocks (IMAGE)
Caption
The metamaterial blocks were used to test the stiffness of blocks with identical external/overall dimensions and mass, but with different numbers of unit cells. The experiments show that the number of unit cells is a crucial parameter influencing the stiffness under compression (left) and torsion (right). The samples were tested under compression in the Metamechanics Lab at the University of Groningen Physics department, using Instron© universal testing machines and under torsion at Instron©’s Applications Laboratory in Boston, USA.
