人体桡骨支架力学模型及承载性能

MECHANICAL MODEL FOR RADIUS SCAFFOLD AND ITS LOAD CAPACITY

  • 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 thethree-dimensional holes in human bones, we propose a method to establishthe mechanical model for human radius scaffold. Mechanical model of humanradius is established in this paper by this method, together with a viscoelasticconstitutive model. According to mechanical properties of themechanical model, we reach the following conclusions: when given a uniaxialpressure, the maximum stress appears in the hole wall, and the relationshipbetween stress and strain is non-linear.
