Abstract Bone is a complex hierarchical material that can be characterized from the microscale to macroscale. This work demonstrates the application of an enhanced homogenization methodology to the multiscale structural analysis of a femoral bone. The use of this homogenization technique allows to remove subjectivity and reduce the computational cost associated with the iterative process of creating a heterogeneous mesh. Thus, it allows to create simpler homogenized meshes with its mechanical properties defined using information directly from the mesh source: the medical images. Therefore, this methodology is capable to accurately predict bone mechanical behavior in a fraction of the time required by classical approaches. The results show that using the homogenization technique, despite the differences between the used homogeneous and heterogeneous meshes, its mechanical behavior is similar. The proposed homogenization technique is useful for a multiscale modelling and it is computationally efficient.

增强均质化技术在股骨结构多尺度分析中的应用

摘要 骨骼是一种复杂的分级材料，可以从微观尺度到宏观尺度进行表征。这项工作展示了增强的均质化方法在股骨多尺度结构分析中的应用。使用这种均质化技术可以消除主观性并降低与创建异质网格的迭代过程相关的计算成本。因此，它允许创建更简单的均质网格，其机械属性使用直接来自网格源：医学图像的信息定义。因此，该方法能够在传统方法所需时间的一小部分内准确预测骨力学行为。结果表明，使用均质化技术，尽管使用的同质和异质网格之间存在差异，但其力学行为是相似的。所提出的均质化技术可用于多尺度建模，并且计算效率高。
