Applications of Metamaterials

With Prof. Lorenzo Valdevit

An overview of the definitions and classes of metamaterials will be provided with a specific emphasis to the applications as lightweight structural materials. The various features of structural metamaterials will be discussed as well as the role of metal additive manufacturing in enabling the scale of these materials. Future pathways to the implementation of these unique materials will be presented.

Applications of Light Metals

With Dr. Carl Söderhjelm

The lecture will first review the prototypical structures and identifying properties of various industrially relevant light metals. Then, several case studies will be presented to demonstrate the novel use of these materials in light weighting across different fields. The lecture will conclude with emerging materials and tools to design them.
