摘　　要：超弹性材料因其优异的力学性能,在工程科学、医疗、人体工程学和制造等领域具有非常广泛的应用。该文将研究不同受载情况对变形血管力学性能的影响,预估动脉损伤的风险程度。结果表明,2阶多项式(Polynomial)模型可精确描述血管组织的力学行为,随着外载荷的增大,动脉组织发生的形变和承受的应力均显著增加,动脉损伤的风险越大。研究成果为超弹性材料的工程制造、医学辅助治疗提供全新思路和方法,具有重要的意义。Hyperelastic materials are widely used in engineering science,medical treatment,ergonomics,manufacturing and other fields because of their excellent mechanical properties.The influence of different loading conditions on the mechanical properties of deformed blood vessels was studied,and the risk of arterial damage was estimated in this paper.The research results show that the second-order polynomial model can accurately describe the mechanical behavior of vascular tissue.With the increase of external load,the deformation and stress of arterial tissue increase significantly,and the greater the risk of arterial injury.The research results provide new ideas and methods for the engineering manufacture and medically assisted treatment of hyperelastic materials,which is of great significance.
