Bonfield和Grynpas1用Currey2提出的纤维增强材料计算得到的理论曲线，比较了杨氏弹性模量值与试件与骨长轴方向夹角的实验数据。由于两条曲线之间的一致性较差，他们得出结论为“…需要另一种模型来解释杨氏模数与取向的依赖关系。1)。在过去的8年里，我的实验室一直在开发这样的替代方案(参考文献3-7)。这是一个两级分级的纤维增强复合材料模型，它似乎更适合描述骨作为纤维增强复合材料的行为。
Bonfield and Grynpas1have compared their experimental data for Young's modulus of elasticity versus the angle of orientation of the specimen to the long axis of bone with a theoretical curve predicted from a calculation for fibre reinforced materials proposed by Currey2. As a result of the poor agreement between the two curves they conclude “… an alternative model is required to account for the dependence of Young's modulus on orientation” (ref. 1). Such an alternative has been under development in my laboratory for the past 8 years (refs 3–7). It is a two-level hierarchical fibre-reinforced composite model which appears to provide a much more suitable description of the behaviour of bone as a fibre-reinforced composite material.
