Abstract: The acoustic black hole (ABH) phenomenon in thinwalled structures with a tailored powerlawprofiled thickness allows for a gradual change of the phase velocity of flexural waves and energy focalization. However, ideal ABH ...

Abstract: A previously proposed planar axisymmetric dynamic vibration absorber (DVA), with embedded acoustic black hole (ABH) features, has been shown to suffer from the very selective coupling with the host structure, thus compromising ...
