Fast active thermal cloaking through PDE-constrained optimization and reduced-order modeling
Carlo Sinigaglia, Davide Enrico Quadrelli, Andrea Manzoni +1
In this paper we show how to efficiently achieve thermal cloaking from a computational standpoint in several virtual scenarios by controlling a distribution of active heat sources.…
Design of arbitrarily shaped acoustic cloaks through PDE-constrained optimization satisfying sonic-metamaterial design requirements
Sebastiano Cominelli, Davide Enrico Quadrelli, Carlo Sinigaglia +1
We develop an optimization framework for the design of acoustic cloaks, with the aim of overcoming the limitations of usual transformation-based cloaks in terms of microstructure c…
Experimental validation of a broadband pentamode elliptical-shaped cloak for underwater acoustics
Davide Enrico Quadrelli, Matteo Alessandro Casieri, Gabriele Cazzulani +2
In this paper we report the numerical design and experimental validation of a pentamode cloak for scattering reduction of elliptical targets in underwater acoustics. Despite being…
Acoustic scattering reduction of elliptical targets via pentamode near-cloaking based on transformation acoustics in elliptic coordinates
Davide Enrico Quadrelli, Gabriele Cazzulani, Simone La Riviera +1
Cloaks for underwater applications designed for actual submarine acoustic stealth are still far from the technological advancement needed for being put in practice. Several challen…
An enhanced parametric nonlinear reduced order model for imperfect structures using Neumann expansion
Jacopo Marconi, Paolo Tiso, Davide E. Quadrelli +1
We present an enhanced version of the parametric nonlinear reduced order model for shape imperfections in structural dynamics we studied in a previous work [1]. The model is comput…
