Nanoindentation of trabecular bone - comparison with uniaxial testing of single trabecula

Original language description

The published mechanical properties of human trabecular bone vary between 1GPa and 15GPa. The cause of this broad discrepancy in results might be in sample preparation, different testing protocols or anisotropy and asymmetry of the micro-samples. The article deals with a comparison between the properties assessed using nanoindentation and properties measured using uniaxial testing of single trabeculae. A novel experimental device was developed for high precision loading control. The strains at the surface of the sample are measured using a high-resolution CCD camera. The strain field is evaluated by precise DIC algorithm applied to whole surface of the loaded sample. The mechanical properties measured on micrometer-sized specimens using both methods (nanoindentation and micro-mechanical testing) are prescribed to FE model. The sample is then loaded according to the experimental procedure. The response of the FE model (stress-strain curve) is compared to results from the tensile test.
