In our previous contributions we established a multiscale, multiphase material model for the simulation of cancellous bone with the novel idea of including the full coupling of mechanical, electric and magnetic effects, which could be used for example, for the early detection of osteoporosis. While our calculations have already shown promising results, our previous approach lacks very important aspects, strongly limiting the applicability of our findings. In this paper we extend our base model by considering the effect of a surrounding medium on our bone specimen, using improved boundary conditions and differentiating between cortical bone, bone marrow and spongy bone to better reflect the physiological properties of bone. We show numerical results and compare our calculations to our previous modeling.

关于耦合骨骼模拟中周围介质和相分裂的影响

在我们之前的贡献中，我们建立了一个用于模拟松质骨的多尺度、多相材料模型，其新颖的想法是机械、电和磁效应的完全耦合，例如可用于骨质疏松症的早期检测。虽然我们的计算已经显示出有希望的结果，但我们之前的方法缺乏非常重要的方面，极大地限制了我们研究结果的适用性。在本文中，我们通过考虑周围介质对骨样本的影响，使用改进的边界条件并区分皮质骨、骨髓和松质骨来扩展我们的基本模型，以更好地反映骨的生理特性。我们展示数值结果并将我们的计算与之前的模型进行比较。
