Title: Elastic metamaterials: numerical simulations and novel architectures

Abstract: Resonant elastic metamaterials are receiving increasing attention due to their extraordinary dynamic properties and novel applications. However, their direct numerical simulation is often prohibitively expensive, similarly to regular composites, which difficulties the exploration of the parameter space for their design. Additionally, their applicability for sound and vibration isolation is often limited by the narrowness of their bangaps. In this talk, we address both of these issues by proposing a novel variational coarse-graining scheme, as well as new metamaterial architectures.
