Project description
Studying small-scale wave propagation at metamaterials
Flexible mechanical metamaterials have surprised scientists owing to their ability to create special transition waves using mechanical instabilities. These waves have been used to study natural phenomena and develop technologies such as soundproofing materials. However, our understanding of how these waves work at small scale is limited. With the support of the Marie Skłodowska-Curie Actions programme, the SnaPump project will study how a single flexible arch snaps between two positions to create these waves. By connecting multiple arches, researchers will design structures that can send controlled waves through them. These waves will be tested for moving fluids such as a pump. The goal is to open new avenues for designing materials that interact with fluids.
Objective
In the last decade, flexible mechanical metamaterials have demonstrated their great scientific potential. By exploiting mechanical instabilities in such structures, researchers have observed the propagation of transition waves yielding both fundamental implications (analog material to understand ferroelectric phase transitions, dislocation motion in crystals) and engineering applications (elective signal transmission, acoustic insulators). Most studies focus on the properties of the waves at the metamaterial level, without analyzing the details of the transition at the building block level. As a result, the mechanisms that govern the propagation of these waves remain poorly understood, which greatly limits their range of application. In this research project I propose a bottom-up approach to investigate this class of phenomena. Specifically, I will experimentally and numerically study the overlooked mechanisms of the snap-through instability of a single bistable arch. This will allow me to design a 1D array of such arches connected via rotating hinges in which an elastic snap-through wave can propagate. I will then put to test this new knowledge in the rarely explored domain of fluid-structure interaction with mechanical metamaterials. Specifically, I propose to exploit these elastic waves for fluid transport applications via peristaltic pumping. This project will yield general rules to design structures that propagate controlled transition waves, and will open new avenues for their use in interaction with fluids.
