Claudia Comi is full Professor of Solid and Structural Mechanics at the Department of Civil and Environmental Engineering of Politecnico di Milano, Italy. C. Comi has authored and co-authored more than 170 scientific publications in various fields of solid and structural mechanics and 5 patents on microsystems. Her main research interests concern theoretical and computational mechanics of materials and structures. Her research activities focus on damage and quasi-brittle fracture modelling, on instability and bifurcation phenomena and nonlocal models for elastoplastic and damaging one-phase and multi-phase materials, including functionally graded materials. Her more recent research is devoted to modelling of auxetic and locally resonant metamaterials, and to design and reliability of microsystems.

In this work, we focus on elastic metamaterials aimed to control wave propagation and on metamaterials designed to obtain a negative or zero thermal expansion coefficient. The role of homogenization in periodic materials and the possibility to define equivalent discrete problems for quasi-periodic materials is discussed with reference to some specific problems. The possibility of integrating metamaterials in microelecromechanical systems (MEMS) is explored.
