本文主要研究饱和度对皮质骨整体弹性性能的影响。我们首先使用Salguero, Saadat & Sevostianov(2014)的微观力学模型来模拟排水皮质骨的各向异性有效弹性刚度,然后使用替代关系(见Sevostianov的评论,2020)来评估饱和的影响。通过与Granke et al.(2011)的实验数据对比,对模型进行了验证。结果表明,考虑了饱和度的影响,模型与实验数据吻合较好。我们还比较了饱和和排水骨骼的各向异性程度,并表明孔隙中生物流体的存在降低了总体各向异性。
This paper focuses on the modeling of the effect of saturation on the overall elastic properties of cortical bone. We first use micromechanical model of Salguero, Saadat & Sevostianov (2014) to model anisotropic effective elastic stiffness of drained cortical bone and then apply replacement relations (see review of Sevostianov, 2020) to evaluate effect of the saturation. The model is verified by comparison with the experimental data of Granke et al. (2011). It is shown that accounting for the saturation makes the model consistent with the experiment data. We also compared the extents of anisotropy of the saturated and drained bones and show that presence of the biological fluid in pores reduces the overall anisotropy.
