Description	Knowledge of trabecular bone behaviour under loading is very important for the bone quality assessment. For investigation of deformation behaviour of trabecular bone a combination of computational and experimental method was used. In this study suitable visco-elasto/plastic material model for single trabeculae was established from numerical simulation of nanoindentation test. The visco-elasto/plastic model with von Mises yield criterion and bilinear isotropic hardening with implicit creep was chosen. Pure elastic material constants can be determined directly from nanoindentation test by Oliver-Pharr method. Other constants determining the plastic and creep behaviour of the model have to be identified indirectly by fitting the load-displacement curve to results from the Finite Element (FE) simulation of nanoindentation test.
