Strongly non-linear continuous model for wave propagation in 2D granular media: derivation and hyperbolicity analysis
Sebastiano Cominelli, Régis Cottereau, Sergey Gavrilyuk +2
In this work, we develop a nonlinear continuum model for wave propagation in two-dimensional granular materials, building on key ideas from Nesterenko's work. Starting from the Her…

Topology optimization of pentamode metamaterials for underwater acoustics
Sebastiano Cominelli, Matteo Pozzi, Francesco Braghin
This study presents an automated topology optimization framework for designing pentamode acoustic metamaterials. It provides precise control over the material effective acoustic pr…
