I reanalysed data from my previous work to determine the extent to which a model for the loading-rate dependence of the fracture of cortical bone, put forward by Carter and Caler, fits this independently derived data set. In particular, the extent to which the generality of the model is vitiated by its ignoring the effect of mineralisation on strength was tested. The model was rather strongly corroborated. In addition, the reanalysed data show that yield strain is strongly strain-rate dependent, but that Young's modulus is rather unvarying over physiological strain rates. The implications of this for hypotheses concerning fracture of bone are discussed.
我重新分析了我之前工作中的数据，以确定卡特和卡勒提出的皮质骨骨折负荷率依赖性模型与这个独立得出的数据集的拟合程度。特别是，测试了该模型因忽略矿化对强度的影响而在多大程度上损害了其通用性。该模型得到了相当有力的证实。此外，重新分析的数据表明，屈服应变强烈依赖于应变率，但杨氏模量在生理应变率范围内相当稳定。讨论了这对有关骨折的假说的影响。
