| 摘 要： | 研究了跟骨、月骨、头状骨松质骨的粘弹性力学性质。对跟骨松质骨纵向、横向、4 5°方向和月骨、头状骨松质骨进行压缩应力松弛、蠕变实验。得出了跟骨松质骨纵向、横向、4 5°方向和月骨松质骨、头状骨松质骨压缩应力松弛、蠕变数据和曲线。用回归分析的方法处理实验数据 ,得出了归一化应力松驰函数 ,蠕变函数及曲线。实验结果表明跟骨松质骨纵向压缩应力松弛、蠕变量均大于横向和 4 5°方向 ;头状骨松质骨初始蠕变量大于月骨松质骨 ,月骨与头状骨 2 h内蠕变量、松弛量差异并不显著。 |

| Abstract: | We have researched the viscoelastic properties of the cancellous bones of the os calcaneus,os lunatum and os capitalum.The compressing stress relaxation expreiment and the creep experiment in the vertical,horizontal and 45 degree directions on the os calcaneus were performed. The data and curve of the compressing stress relaxation and creep were obtained. By masing regression analysis we worked out the compressing reduced stress relaxation and creep functionns and curves.The results show that the quantities of compressing stress relaxation and creep of the calcaneus in the vertical direction are larger than those in the other two directions. The initial quantities of creep of the os capitalum are larger than those of the os lunatum, and there are no significant different betweences the quantities of stress relaxation of the cancellous bones of the os lunatum and os capitalum. |
