Abstract:
In this paper, combined with the finite element (FE) method and optimization theory, a strain energy criterion is used to simulate and predict the bone remodeling. The strain energy density is taken as the mechanical stimulus. The bone remodeling is described as the changes of material distribution, which can represent the process of bone remodeling. By remodeling simulation of a two-dimensional proximal femur, a three-dimensional proximal femur and bone fracture healing plastic process, we demonstrate that this criterion can produce a realistic apparent density distribution in the proximal femur, and this criterion can well illuminate the mechanism of bone fracture healing plastic process.
