Abstract |
|
A structure consisting of pivoting cubes is presented. It has zero Young’s modulus and zero bulk modulus. Poisson’s ratio has large negative values in all directions; the structure exhibits anisotropy in Poisson’s ratio. The structure is compliant in tension but rigid in torsion and bending. The Cosserat characteristic length tends to infinity. |
