PERIODO: GIUGNO 2018

Il corso sarà tenuto dal prof. Sondipon Adhikari del College of Engineering of Swansea University - UK

Mechanical metamaterials have surged to the forefront over the past
five years against the backdrop of the unprecedented developments in
optical, electromagnetic and acoustic metamaterials. Metamaterials are
designer media with periodic units comprised of unique tailor-made
geometry (see Fig. 1) and patterns that produce extraordinary and
unusual bulk properties not seen in conventional materials. The effective properties of metamaterials originate from the geometry and structure, and not from the intrinsic property of the constitutive material. Intense research in recent years show truly exciting developments such as ultralight metamaterials approaching theoretical strength limit, pentamode materials,
negative refraction elastic waves elastic cloaking and hyperbolic elastic metamaterials. This course will introduce essential techniques for the analysis of cellular mechanical metamaterials.
This is a research-led teaching course and consequently the topics to be covered are in general not systematically available in any books but scattered in research papers including those authored by the lecturer. The lecture course will cover the following topics in depth:
1. Introduction to mechanical metamaterials
2. Static structural mechanics of cellular metamaterials – homogenised properties
3. Effective mechanical properties of disordered cellular metamaterials
4. Mechanics of viscoelastic cellular metamaterials,
5. Homogenised properties of general multiplanar and multiscale 2D metamaterials
6. Dynamic homogenisation of cellular metamaterials
7. Multiphysics wave characteristics of piezoelectric metamaterials
8. Wave propagation in disordered cellular metamaterials
