WP1 was concerned with the development of modelling tools to tackle theoretical or numerical challenges related to multi-scale characteristics of the vibroacoustics in periodic media. Homogenization, model reduction techniques and wave propagation methods for periodic vibroacoustics have been developed. Loading effects and spatially correlated loading of periodic structures are also examined. A full winter school was devoted to this first objective.
The objective of WP2 was to perform topological assessment on the vibroacoustics of periodic media. A special emphasis was made on geometry connectivity and using innovative techniques (e.g. Kirigami, multi-layer core topologies) to design and manufacture periodic honeycomb structures for wave propagation enhancements. A full autumn school is planned to cover this objective.
WP3 successfully addressed the effects of constitutive material classes on the vibroacoustic response of periodic media. These include poro-elastic materials, auxetic materials, viscoelastic add-ons and will pursue with the influence of perforating strategies. Applications are already planned in the low frequency range using combinations and manufacturing of nanostructured materials, inclusions with gradient, poro-elastic and auxetic behaviour. A full spring school is planned for this objective.
WP4 follows the 4th Objective and is dedicated to integration issues and industrial applications. The vibroacoustic performances of the periodic structures has been investigated in terms of robustness (uncertain periodic and quasi-periodic configurations). A full summer school was devoted to this objective.
