Abstract
Acoustic drag suppression in periodic cellular solids. Two geometric conditions — force monopole cancellation (M₀=0) from centrosymmetric cells and a kinematic gap from under-constrained Plateau vertex degree (z=4) — suppress phonon radiation from localized excitations. Verified on three Voronoi foam structures (C15 Laves, Kelvin BCC, Weaire-Phelan) with 82 tests. Anharmonic lifetime ~10⁸ periods at 1% strain.
