人的密质骨的力学性能

本文把骨组织看作是一种材料和骨骼系统的粘弹性结构元件,评述了它们的力学性能.首先描述了骨的结构,包括宏观结构、微结构和超微结构.随后是骨的力学性能.第三部分介绍了哈弗氏骨的力学模型.笔者指出,单个哈弗氏骨可考虑为正交铺设的胶原纤维增强的粘弹性厚壁筒.最后讨论了哈弗氏骨的应力-应变关系.显然,简单的弹性关系是不可用于实际的. 

THE MECHANICAL PROPERTIES OF HUMAN COMPACT BONE

The properties of the bone tissue as a material and the bones ns viscoelastic structural elements of the skeleton are reviewed and summarized. The first part of this work describes bone structure including Macro-, Micro-and Ultra-structure. The second concerns the mechanical properties of bone. The third introduces the mechanical models of Haversian osteon. The authors point out that a single osteon can be considered as a viscoelastic thick-walled tube which is reinforced by the fibres of cross-ply. The last part discusses the stress-strain relationship of Haversian osteon. It is seen that the simple clastic relations were unacceptable in practice.
