| 摘 要： | 针对人体骨组织三维网状孔洞分布特点,得到了一种建立人体骨支架力学模型的方法.利用该方法获得了人体桡骨力学模型,导出了桡骨黏弹性本构模型.通过对桡骨力学模型的承载性能分析,得出:当桡骨受到单向轴向压力时,最大应力出现在通孔孔壁上,且应力与应变的关系是非线性的.

| Abstract: | Based on the distribution of the three-dimensional holes in human bones,we propose a method to establish the mechanical model for human radius scaffold.Mechanical model of human radius is established in this paper by this method,together with a viscoelastic constitutive model.According to mechanical properties of the mechanical model,we reach the following conclusions:when given a uniaxial pressure,the maximum stress appears in the hole wall,and the relationship between stress and strain is non-linear. |
