摘要/Abstract

摘要： 研究了正常国人新鲜尸体腹主动脉血管的粘弹性力学性质.通过进行腹主动脉血管的应力松弛、蠕变实验得出了腹主动脉应力松弛、蠕变数据及曲线.用回归分析的方法处理实验数据,得出了归一化应力松弛函数和归一化蠕变函数及曲线,并对实验结果进行了分析和讨论.

关键词: 腹主动脉, 粘弹性, 归一化应力松弛函数, 归一化蠕变函数

Abstract: Researches focus on the aorta abdomen veins of the normal Chinese fresh dead bodies. Experiments are carried out on the stress relaxation and creep, thus obtaining the stress relaxation and creep data and curves of the aorta abdomen under the situation of constant stress and strain. Through regression analysis the authors obtain the reduced stress relaxation and creep functions. Finally, the results of the experiments* are analyzed and discussed.

Key words: aorta abdomen, viscoelasticity, reduced stress relaxation function, reduced creep function
