The Stability of bucked icosahedral structures

On peut construire une famille d’icosaèdres concaves dont chaque icosaèdre serait composé de huit triangles équilatéraux d’une longueur d’arête e et de 12 triangles isocèles d’une longueur d’arête longue 2a. Dépendant de la valeur du ratio 2a/e, le polyèdre en résultant peut etre rigide, infinitésimalement mobile ou bistable.
