Резюме: The complex hierarchical structure of bone is a living material characterized by its significant mechanical properties. Bone is subject to constant physiological and mechanical stresses, so bone quality constantly changes over time through the process of bone remodeling. Based on experimental results obtained by [1] and [2], we specifically concentrate on bone remodeling that occurs in the cortical/trabecular zone or transition zone. The objective of this work is to model the femoral bone remodeling process under dynamic and quasi-static loading describing its physical activity for different high, medium, and low levels to generate a numerical model of the femoral bone cell transduction phenomenon caused by different levels of mechanical loading as a function of time. To achieve this objective, the finite element method was used. According to this work, it was shown that bone remodeling plays the role of a reorganization process to maintain a good balance in the cortical/trabecular area of the bone, the bone volume fraction and the transduction signal showed variable responses. These results may provide a tool to define the causes of altered bone remodeling and provide a medical solution.
