Compact bone specimens from many species were examined to determine the relationships, in tension, between mineral content, Young's modulus, yield stress, yield strain, post-yield stress, post-yield strain, ultimate stress, ultimate strain and work under the stress-strain curve. Yield strain varied much less than the post-yield strain, and yield stress was strongly dependent on Young's modulus. Mineral content was a rather poor predictor of yield stress. However, post-yield events were predicted better by mineral (calcium) content than by Young's modulus. The greater the mineral content the less the post-yield work under the curve and the less the increase in post-yield stress and strain. The findings are compared with those of Les et al. who compressed specimens from equine metacarpals. Where they can be compared, the results are consistent with each other.
对来自许多物种的致密骨标本进行了检查，以确定在拉伸状态下矿物质含量、杨氏模量、屈服应力、屈服应变、屈服后应力、屈服后应变、极限应力、极限应变以及应力-应变曲线下的功之间的关系。屈服应变的变化远小于屈服后应变，并且屈服应力强烈依赖于杨氏模量。矿物质含量对屈服应力的预测能力相当差。然而，与杨氏模量相比，矿物质（钙）含量对屈服后事件的预测效果更好。矿物质含量越高，曲线下屈服后的功越少，屈服后应力和应变的增加也越少。将这些发现与莱斯等人对马掌骨标本进行压缩试验的结果进行了比较。在可比较的情况下，结果相互一致。
