Using a recently developed elasticity theory for the mechanics of microstructured materials (homogenization theory) the dependence of trabecular bone strength on volume fraction of bone was calculated. Using a spherical void model for trabecular bone, the results showed a quadratic dependence of strength on solid volume fraction for loadings along the principal strength axes, and a cubic dependence for loading in shear. These results are consistent with the theoretical predictions of other investigators and with experimental results. The assumed failure mechanism was tensile tissue rupture rather than the more commonly assumed trabecular buckling failure.
