Mechanics of Mechanical Metamaterials

November 18 - November 22

About the Course:

Overview:

The course gives an overview of mechanical metamaterials and the aspects of modelling them. A specific emphasis will be laid on the discussion of static and dynamic response of mechanical meta materials through super cell and phenomenological models. Micromechanics based constitutive models to describe the mechanical behaviour of fibre network metamaterials will be discussed. Recent advances such as origami-based folding and energy absorption capabilities of metamaterials will also be discussed.
