Descritivo da Vaga:
Tipo de Atividade: The development of materials with desired dynamic properties is a booming branch in structural mechanics. A promising approach is to introduce a mesoscopic structure to achieve a macroscopic effect. Mesoscopic can refer to any length scale between the molecular level and the size of a macroscopic sample. Such materials are often referred to as metamaterials. Exotic dynamic behavior, such as vibration isolation within a certain frequency band or a negative refraction ratio, is studied theoretically and experimentally. In most cases, periodic structures are used since their behavior can be modelled in a fast and straightforward way. Finite element simulations on a single unit cell predict how waves can expand in the material. However, these simplified models assume the absence of boundaries. It is not clear how these theoretical predictions can be related to realistic, finite sized samples. This project has two goals: - Compare the finite element simulation results of wave propagation in a periodic plate, using two methods: the periodic model and a full scale model of a finite plate with boundaries. - Measure the dynamics of several prototype plates and set up a method to calculate the wave energy flow in the samples using the experimental data. This gives insight into the metamaterial’s dynamics at the edges and the efficiency of the isolation frequency bands. The two tasks are performed independently by the intern, in close collaboration with the lab’s scientists. The Laboratory for Acoustics/Noise Control is part of the Swiss Federal Laboratories for Materials Science and Technology. We investigate innovative materials for improved acoustical and vibration behavior, such as foams and metamaterials.
