Résumé. — Nous décrivons ici les résultats de nos essais de représentation d'agrégats non cristallins, formés d'empilements denses et comportant jusqu'à plusieurs centaines de sphères molles. Nous montrons que des motifs à symétrie dodécahédrique peuvent être assemblés pour former de grandes structures centro-symétrique basées sur le réseau radial 56. Ces représentations d'agrégats sont alors utilisées, en même temps que des modèles relaxés de groupements aléatoires de sphères pour montrer que de grands domaines ordonnés peuvent exister dans des matériaux amorphes.
