. En-Évidence-par-dorrer and . Rühe, il semblerait que la ligne de contact explore les bords des trous comme des défauts sur lesquels elle s'accroche, et étant donné leur grande taille (ils sont dix fois plus larges que les plots) l'adhésion est élevée. On constate d'ailleurs que dans le cas des trous, ?cos? semble décroître quand ? augmente, or sur des surfaces couvertes de micropiliers l'inverse est observé [79]. Ceci confirmerait le scénario ci-dessus. Il serait alors intéressant de comparer cette hystérésis à celle créée par le négatif des surfaces à trou utilisées ici
