Fracture and size effect in mechanical metamaterials
J. Ulloa, M. P. Ariza, J. E. Andrade +1
We resort to variational methods to evaluate the asymptotic behavior of fine metamaterials as a function of cell size. To zeroth order, the metamaterial behaves as a micropolar con…

Homogenized Models of Mechanical Metamaterials
J. Ulloa, M. P. Ariza, J. E. Andrade +1
Direct numerical simulations of mechanical metamaterials are prohibitively expensive due to the separation of scales between the lattice and the macrostructural size. Hence, multis…
