The Research Of Artery On The Static Mechanics Property

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.
