Acoustic Black Hole (ABH) is a technique for passive vibration control that was recently developed within the Structural Dynamics and Vibroacoustics communities. ABH effect is achieved by embedding a local inhomogeneity in a thin-walled structure, typically a beam or a plate. If the speed of an incoming wave can vanish inside the ABH, it follows that this object behaves as a wave trap that extracts elastic energy from the host medium without, in principle, ever releasing it. You will design and model the ABH beam in this project, and you will learn how material inhomogeneity can reduce a system's vibration.
