Elastically-isotropic mechanical metamaterials : theory and experiments

Lightweight engineering requires the development of low-density materials featuring high mechanical properties with an emphasis on high-specific stiffness and strength. Besides improvement in the composition of bulk materials, high specific mechanical properties are obtained by carefully architecting materials through the controlled introduction of porosities. The recent rise of additive manufacturing allows for the manufacturing of complex structures at the material length scale, opening an unprecedented design space of metamaterials. Amongst this design space, this thesis is concerned with the conception of three-dimensional isotropic metamaterials, a particularly important class of mechanical metamaterials exhibiting direction-independent behavior at the macroscopic level.
