| الوصف: | The purpose of this work is to propose an enhancement of Doblaré and García's internal boneremodelling model based on the continuum damage mechanics theory. In their paper, theystated that the evolution of the internal variables of the bone microstructure, and its incidenceon the modification of the elastic constitutive parameters, may be formulated following theprinciples of Continuum Damage Mechanics, although no actual damage was considered. Theresorption and apposition criteria (similar to the damage criterion) were expressed in terms ofa mechanical stimulus. However, the resorption criterion is lacking a dimensional consistencywith the remodelling rate. We here propose an enhancement to this resorption criterion,insuring the dimensional consistency while retaining the physical properties of the originalremodelling model. We then analyse the change in the resorption criterion hypersurface in thestress space for a 2D analysis. We finally apply the new formulation to analyse the structuralevolution of a 2D femur. This analysis gives results consistent with the original model butwith a faster and more stable convergence rate. |
