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.

骨骼是一种复杂的等级材料，可以从微观到宏观进行表征。这项工作演示了增强的均质化方法在股骨多尺度结构分析中的应用。使用这种均质技术可以消除主观性，并减少与创建异构网格的迭代过程相关的计算成本。因此，它允许使用直接来自网格源的信息（医学图像）来定义其机械性能来定义更简单的均质化网格。因此，这种方法能够在经典方法所需的一小部分时间内准确预测骨骼的力学行为。结果表明，使用均质技术，尽管使用的均质和异质网格之间存在差异，其机械性能相似。提出的均化技术可用于多尺度建模，并且计算效率高。
