摘要
由动脉血管零应力状态和无载荷状态的几何参数，分析计算了其无载荷状态下的残余应变，并由残余应变分布和平衡方程，用最小二乘法拟合七参数应变能密度函数的参数，进而确定了动脉壁在零应力状态下的本构方程。
The residual strains of arteries wall are calculated from measuring the configurations of blood vessels in zero stress state under non-loading condition.Furthermore,the Functional parameters of the strain energy density are calculated from the distribution of residual strains and the balance equation using the least square fit.Therefore,the constitutive equation of arteries could be determined through analying the arteries in zero stress and non-loading conditions.
