Dynamic analysis of metamaterials for industrial applications: numerical predictions and experimental results

Metamaterials hold promise for enhancing vibroacoustic performance in sectors like automotive, aerospace, and infrastructure. Advanced design methodologies enable these materials to create targeted bandgaps and suppress unwanted waves and vibrations. This research focuses on analyzing vibroacoustic metamaterials, emphasizing the bandgap phenomenon through numerical predictions and experiments. It examines how variations in geometry, size, periodicity, and material properties affect the bandgap. The study compares numerical simulations with experimental results to validate the design process. By manipulating pattern parameters, the research aims to optimize bandgap characteristics of a metal plate for industrial applications, ensuring the design's reliability and effectiveness for practical use.
