REsonant Metamaterials for Train-Induced ground vibration mitigation

REMoTIon proposes an innovative Compact Resonant Wave Barrier (CRWB) to mitigate railway-induced ground vibrations. Engineering implementation of current pile barriers is limited due to their large dimensions, especially in city centers. Instead, by exploiting the locally resonant metamaterials concept, the proposed research framework allows for designing barriers with practical engineering dimensions. The main research objectives of the project include: (i) analytical design of CRWB guided by dispersion laws by employing Multiple Scattering theory, (ii) numerical design and optimization of CRWB exploiting a mixed wave finite element method and machine learning technique, and (iii) fabrication and testing of CRWB on the field.
