Identification of higher-order continua equivalent to a Cauchy elastic composite

Dear Mechanician,

A novel method for the identification of higher-order continua equivalent to a Cauchy composite has been published, as a result of the collaboration between the following two ERC projects:

Engineering structures are made out of materials and as such there is a natural hierarchy in which a material’s intrinsic properties contribute to shaping up the structure’s response. It is possible however to reverse this hierarchy and engineer materials that are made out of structures. In this case, the intrinsic properties of a material are shaped by the structural response. Such a configuration can only be realized with a repeated structure, forming an array of identical unit cells.
