۱Geometric Feedback in the Bone Remodeling Equation: A Modification on the Adaptive Elasticity Model
اطلاعات انتشار: سیزدهمین کنفرانس سالانه مهندسی مکانیک، سال
تعداد صفحات: ۸
In this paper we propose a new set of constitutive equations for bone remodeling that uses the specific surface instead of volume fraction. The theory of small–strain adaptive elasticity proposed by Cowin and Hegedus and a surface remodeling equation are derived to develop the remodeling theory. A relationship between net bone cell activity, bone material property and mechanical stimuli is derived. For illustration, the rate of change of trabecular remodeling is derived for selected geometries. With this model, the effect of bone geometry and mechanical stimuli on the rate of remodeling can be studied.<\div>

Everyday activities may cause microdamage in bones that is repaired through continuous remodeling. An imbalance in this remodeling process caused by abnormal mechanical demands, fatigue or disease, may predispose bone to more pronounced fracture injuries. The remodeling process is generally viewed as a material response to functional demands that is governed by an intricate relationship between bone
reinforcement and resorption. Here, we analyze the competition between damage and internal remodeling in bones. The analysis is based on a consistent thermodynamic framework of bone remodeling, involving a chemical reaction and mass transfer in the presence of microcracks.<\div>

Based on the idea of bone mineralization and formation on chemically functionalized carbon nanotuebes (CNTs), a representative volume element of hydroxyapatite (bone mineral phase ) aroun a CNT is considered to determine its mechanical response to exial loading.<\div>
