| 摘 要： | 研究了正常国人新鲜尸体股骨上端松质骨的压缩粘弹性力学性质。对股骨上端松质骨纵向、横向、45°方向试样进行了压缩应力松弛、蠕变实验 ,得出了股骨上端松质骨 3个方向的应力松弛、蠕变数据和曲线。对实验数据进行归一化处理 ,得出了归一化应力松弛、归一化蠕变函数及曲线。实验结果表明 ,股骨上端松质骨纵向组应力松弛、蠕变量均大于横向组和45°方向组。股骨上端松质骨为各向异性材料。 |
| 关 键 词： | 股骨上端松质骨 纵向 横向 45°方向 粘弹性 |

| Abstract: | Compressing viscoelasticity of cancellous femur upper part of normal fresh corpse of our country was studied experimentally including compressing stress relaxation and creep test in 3 directions:longtitudinal,transversal,and in 45°direction.Normalized stress relaxation and creep functions were regressed from obtained data and illustrated in curves.Results showed both longtitudinal stress relaxation and creep of cancellous femur upper part are larger than those in other 2 directions,demonstrating it is an anisotropic material. |
| Keywords: | cancellous femur upper part viscoelasticity anisotropy |
