文摘

Examined rate-dependent role of fluid in bone using a poroelastic micro-FE approach. Hydraulic stiffening depends highly on bone microstructure. Poroelastic rate-dependency in bone is more significant in cortical samples. Hydraulic stiffening in bone depends highly on loading and boundary conditions. Discussed suitable boundary conditions for in vivo mechanical characterization.
