Behavior of trabecular bone is investigated using real nanoindentation and finite element simulation. Two different plasticity criteria for material model of trabeculae are tested, namely von Mises and Drucker-Prager. Von Mises criterium is extended bilinear isotropic hardening. Constants needed for numerical material model are obtained from fitting procedure of a experimetal load-displacement curve.
