骨结构特征的详细描述在文献中比比皆是：然而，骨的机械性能，特别是那些在微观和纳米结构水平，仍然知之甚少。本文综述了现有的力学数据，重点是骨的复杂层次结构与其力学性能之间的关系。通过应用混合物公式的复合规则来预测骨的机械性能的尝试仅取得了适度的成功，这清楚地表明，准确的模型应包括在骨材料亚单位之间传递载荷所涉及的分子相互作用或物理机制。在获得关于各种有机和无机成分之间相互作用的更多信息之前，这种模型是无法构建的。因此，除了在“结构水平”的研究之外，还需要在“材料水平”上进一步研究力学性能，以填补我们现有知识中的差距，并实现对骨的力学性能的完整理解。(C)1998年，妇女平等研究所。由Elsevier Science Ltd.出版，版权所有。
Detailed descriptions of the structural features of bone abound in the literature: however, the mechanical properties of bone, in particular those at the micro- and nano-structural level, remain poorly understood. This paper surveys the mechanical data that are available, with an emphasis on the relationship between the complex hierarchical structure of bone and its mechanical properties. Attempts to predict the mechanical properties of bone by applying composite rule of mixtures formulae have been only moderately successful, making it clear that an accurate model should include the molecular interactions or physical mechanisms involved in transfer of load across the bone material subunits. Models of this sort cannot be constructed before more information is available about the interactions between the various organic and inorganic components. Therefore, further investigations of mechanical properties at the 'materials level', in addition to the studies at the 'structural level' are needed to fill the gap in our present knowledge and to achieve a complete understanding of the mechanical properties of bone.
