Approche structurale de la mécanique du cytosquelette: solide alvéolaire vs modèle de tenségrité

To describe the relationship between shape and rigidity of cultured cells, we attempt to figure out the similarities and discrepancies in geometrical and mechanical behaviors between a continuous cellular solid and a tensegrity structure. The rigidity of the structure is characterized by elementary bending in cellular solid and a spatial rearrangement of the elements in tensegrity model. This spatial reorganization tends to decrease the scale factor influence in tensegrity model. This factor has a major effect in cellular solid model in spite of the lack of internal tension.
