摘要

本文介绍了应力模式和变形的动脉与动脉瘤在压力的变化。当动脉壁的薄弱部分在压力下凸出时,就会出现动脉瘤。为了做出正确的治疗决定,必须了解病情的形成和发展。本文利用有限元分析软件ANSYS,采用超弹性材料模型对动脉中梭状动脉瘤的形成进行了有限元分析。我们提出了不同血压对动脉壁变形的影响,并将其与正常动脉进行了比较。本工作可为该领域的研究提供参考。

Analysis of the Formation of an Aneurysm in Arteries Through Finite Element Modeling Using Hyper-Elastic Model
This paper presents the stress patterns and deformation in an artery with an aneurysm under a variation of pressure. An aneurysm occurs when a weak portion of artery wall bulges out under pressure. To make a proper treatment decision, one must understand the formation and growth of the condition. In this article, finite element analysis of the formation of fusiform aneurysms in arteries is presented using the hyperelastic material model by employing ANSYS. We present the effect of different blood pressures in the deformation of the weakened arterial wall and also compare it with a normal artery. This work can be used as a reference for research in this area.
