Abstract

Un système d'atténuation et d'accord pour atténuer une explosion ou un impact comprend : un ensemble couche d'accord dont l'impédance acoustique est choisie pour accorder des ondes de contrainte résultant de l'explosion ou de l'impact à une ou plusieurs fréquences d'accord spécifique ; et un ensemble couche de dissipation comprenant un matériau viscoélastique dont la fréquence d'amortissement critique correspond à au moins une ou plusieurs fréquences d'accord spécifiques.
