[Cyclic loading of a transverse isotropic poroelastic cylinder: a model for the osteon]
The poroelastic problem associated with a hollow cylinder under cyclic loading is solved. Both fluid and solid phases are supposed compressible. Solid matrix is modeled as an elastic transverse isotropic material. An explicit close-form solution for the steady state is obtained. This cylinder is considered as a model for an osteon, the basic unit of cortical bone. The fluid flow distribution as a function of poroelastic properties and cyclic loading is discussed, as this could influence bone remodeling.
L'étude d'un cylindre poroélastique creux sollicité par déplacements axiaux cycliques est menée dans le cadre de la théorie de la poroélasticité. Les phases fluide et solide sont supposées compressibles. Le matériau a des propriétés transverse isotrope. Une solution analytique explicite du problème posé en régime établi est obtenue. Le cylindre considéré représente un modèle d'ostéon, élément unitaire du tissu osseux. La répartition de la vitesse moyenne d'écoulement du fluide, en fonction des caractéristiques poroélastiques du matériau et de celles du chargement imposé, est étudiée pour sa probable influence sur le remodelage osseux.
