Non-linear homogenization of polymer composites with porous inclusions
Résumé
We homogenize the mechanical properties of a two-phase polymer composite, made of a polyurethane matrix containing porous spherical silicone-based inclusions, and designed to be used for wave control as a local resonant insulator. First we consider a homogenized energy for the spherical inclusions, an expression obtained by an explicit method. Then, we couple inclusions and matrix by means of the secondorder tangent method. Direct finite element simulations allow some comparisons with available experiments.
