Abstract
The fast growing field of metamaterials opens a number of new opportunities and applications but, at the same time, introduces many challenges in the design and modeling. The two scale asymptotic homogenization appears as a promising tool for the design and optimization of systems composed of metamaterials. In this contribution, we discuss the role of homogenization in the development of practical applications of metamaterials. Focus will be in particular on two significant examples: the optimization of auxetic metamaterials for energy absorption and the design of a system for energy localization that includes locally resonant materials. In both cases, the metamaterial is substituted with an equivalent homogenized continuum allowing for a fast parametric optimization and leading to a significant computational advantage.
