哈氏系统破坏的微观结构分析

Mechanical Failure in Haversian Systems on the Basis of Microstructure

  • 摘要: 本文旨在通过五个长骨试样在五个不同载荷等级(2KN,3KN,4KN,5KN和6KN)的抗压试验,观察哈氏系统(Haversian System)——哈氏骨板和哈氏管——的变化情况.由一组显微照片可以十分清晰地看出:(1)在载荷等级低的情况(2KN),哈氏管几乎与未受力时一样,哈氏骨板亦然;(2)在载荷等级高的情况,哈氏骨板最弱的部分最先变形;(3)随着载荷的增加,哈氏系统破坏的形式十分复杂,断裂总是发生在骨的结合缘处. 同时,测量了变形后的哈氏骨板和哈氏管的有关尺寸.对试验中所观察到的现象,用线性粘弹性力学的理论予以解释.最后提出了骨单位为纤维增强的厚壁筒模型.
