【摘要】 本文首先对血管壁静态力学特性研究历史及现状做了一下简要的介绍，特别是关于血管壁本构方程的研究做了比较详细的阐述。本文是在先辈工作的基础上，借助于应变能密度函数，给出血管壁本构方程的三维表达形式（七参数），并借助于先进的实验设备及方法，拟和出本构方程的七个物质参数。 在本次实验研究中，采用了新的实验设备及新的实验手段—无接触测量方法及标准化的实验方案，从中得到了大量的实验结果，并用自行编制的软件对其颈动脉的张开角以及拟合所需各种静态数据进行了比较精密的测量，从而将这些值运用于本构方程的拟合。同时，给出了实验时轴向力及拉力随外径变化的曲线及拟合后轴向力及压力随外径变化的曲线。最后，对实验的结果及拟合后的结果进行分析及讨论（考虑残余应力和不考虑残余应力的情况）。更多还原

【Abstract】 Beijing Polytechnic University, Beijing, 100022, ChinaStudent: DiaolinaTutor: Li Xiaoyang , Prof.The history and the present status of the static mechanics properties are introduced at the beginner in this paper,especially the investigation into the constitutive equation is expatiated with detail.This paper,on the bases of the predecessor work,with the help of the strain energy function,the three-dimension expression on the artery constitutive equation is derived (seven coefficients),In addition,in virtue of the advanced experimental equipment and the method,the seven parameters are fitted.In the stage of the experiment research,the new equipment and new mode ,noncontact measure method and the standardized project are adopted ,from which the number of the result are educed.the opening angles of the carotid and various static data needed in the stage of the fitting are measured with the software written by ourself,these data are applied to the fitting.In the same time,the curve of the internal pressure and pull with the vary of the exterior radius are presented.At the end ,the discussion about these results are carried out.更多还原
