摘要
本文对新鲜人颅骨小试件分别进行了压缩和拉伸的松驰、蠕变试验,运用线性粘弹性理论导出准静态下颅骨压缩和骨板拉伸时的粘弹性本构议程。利用Wood骨板单向拉伸的c～8曲线(ε=0.005/s～150/s),与出骨板拉伸时的动态粘弹性本构方程。讨论了准静态和动态粘弹性本构方程之间的关系。给颅脑损伤的理论分析和模拟试验研究提供了实用的基础资料。
<ABSTRACT>
On the basis of results of relaxation and creeping tests of fresh hu-
man cranial bone during compression and compact bone during tension,
by use of the linear viscoelastic theory, this paper deduced relaxation
modulus function, creeping compliance function anel constitutive equa-
tion in quasi-state under compression and tension. By use of results of
compact bone tension tests at strain rates ranging from 0. 005 to 150s-1,
the constitutive equation in the dynamic-state for the compact bone in
tension was determined. This constitutive equation might be used as the
basic equation in theoretical analysis and calculation for the diagnosis
of head injury.
