Micro-Macro Acoustic Modeling of Heterogeneous Foams with Nucleation Perturbation

<div class="section abstract"><div class="htmlview paragraph">The properties of a polyurethane foam are greatly influenced by the addition of graphite particles during the manufacturing process, initially used as a fire retardant. These thin solid particles perturbate the nucleation process by generating bubbles in their immediate vicinity. A large body of work has focused on foams that are reasonably homogeneous. In this work, we...
