    This paper deals with development of a numerical visco-elasto plastic material model for a single human trabeculae and its application on a complex sample. The elastic constants for this model were obtained directly from nanoindentation, remaining ones were determined indirectly from Finite Element Analysis (FEA). Identified material model was used for a Finite Element (FE) model of complex cylindrical sample of human trabecular bone. The geometry of the FE model was obtained from X-ray micro Computed Tomography. To verify the ability of the material model to describe deformation behavior of trabecular bone a cylindrical sample was incrementally loaded in compression and the deformed microstructure repetitively scanned.
