چکیده
PO Box 513, 5600 MB Eindhoven, The Netherlands Introduction Osteoporotic fractures mainly occur at sites with relatively large amounts of trabecular bone. The devastating effects of such fractures can be prevented with accurate predictions of trabecular bone strength. Micro-finite element (μFE) models have been successfully used to study and predict trabecular bone elastic and yield properties. Strength predictions, on the other hand, require the post-yield behavior of trabecular bone tissue. Due to experimental difficulties this data is not available. The purposes of this study were to (1) indirectly determine the tissue properties using μFE models by iteratively fitting of simulation to experimental results for a trabecular bone specimen and (2) test to what extent the post-yield behavior of other similar specimens can be predicted when using these parameters in μFE analyses.
