Abstract

L'invention vise à créer un moyen de structuration d'un corps structure rigide qui permette un rapide changement entre un état fluide et un état corps structure rigide pour obtenir la forme souhaitée. A cet effet, un grand nombre de sphères de taille uniforme est enfermé dans un sac, et une contrainte de compression est appliquée aux sphères par un moyen de réduction du volume du sac pour limiter le groupe des sphères à un état plus dense de la structure rigide. Cela permet d'obtenir un corps structure rigide de la forme souhaitée. On obtient ainsi un procédé de mise en forme du corps structure lui permettant de passer rapidement d'un état fluide à un état corps structure rigide et vice versa pour qu'il puisse être adapté rapidement à diverses formes et remodelé de manière répétée.
