402-0801-66L Mechanical Metamaterials

Abstract	A mechanical metamaterial derives its static or dynamic properties not from its microscopic composition but rather through its clever engineering at larger scales. In this course we introduce the basic principles behind the design of modern mechanical metamaterials such as the use of Bragg scattering, local resonances, topological band-structures, and non-linear effects.
Objective	The students should get acquainted with a modern toolbox in the design of mechanical metamaterials. Equipped with the knowledge of the key design principles, the students will be able to choose the appropriate approach to create a metamaterial with a pre-defined functionality either for dynamic applications such as vibration isolation, wave-guiding, or the design of a heat-diode, or static properties such as stress absorption or the design of mechanisms used in robotics.
