Mechanical metamaterials are microstructured mechanical systems showing an overall
macroscopic behaviour that depends mainly on their microgeometry and microconstitutive …

In this paper, we account for the research efforts that have been started, for some among us,
already since 2003, and aimed to the design of a class of exotic architectured, optimized …

In order to design the microstructure of metamaterials showing high toughness in extension
(property to be shared with muscles), it has been recently proposed (Dell'Isola et al. in Z …

The problem of the synthesis of second gradient (meta) materials, via architectured
microstructures made of micro-lattices, has been solved (Alibert et al., 2003; Seppecher et …

In the problem of the synthesis of metamaterials, the pantographic architecture revealed
remarkable potentialities. Indeed it allowed for the synthesis of second gradient 2D …

The development of additive manufacturing methods, such as 3D printing, allows the design
of more complex architectured materials. Indeed, the main structure can be obtained by …

Recently growing attention has been paid to the particular class of metamaterials which has
been called pantographic. Pantographic metamaterials have the following peculiar …

In this paper we describe a three-scales homogenization process which we use to
determine a macroscopic model for pantographic metamaterials. The smallest scale refers to …

Pantographic structures are examples of metamaterials with such a microstructure that
higher-gradient terms' role is increased in the mechanical response. In this work, we aim for …

In the standard asymptotic micro-macro identification theory, starting from a De Saint-Venant
cylinder, it is possible to prove that, in the asymptotic limit, only flexible, inextensible, beams …
