Abstract

Ces travaux montrent la pertinence et l'utilité de la modélisation du cytosquelette des cellules par systèmes mécaniques précontraints. Ces recherches s'inscrivent dans le champ de la biomécanique cellulaire et tissulaire et deux applications sont proposées. On présente tout d'abord la recherche de forme d'une cellule isolée par modèles de tenségrité non réguliers, puis on propose une combinaison entre les modèles granulaires et l'analogie de tenségrité. L'extension prospective aux assemblages multicellulaires avec notion d'autocontrainte partagée, par modèles de grilles de tenségrité est ensuite présentée.
