Abstract

A review of studies of the mechanical properties of human and animal heart tissues has been performed. On the basis of published data, a form of approximating function is found for the dependence of Young’s modulus of the ventricles of the human heart on the magnitude of the deformation. The average values of Young’s modulus and other elastic constants were calculated and compared with the known experimental values. The coefficients C₁ and C₂ of the two-parameter hyperelastic myocardial Mooney–Rivlin model are calculated.

心肌力学性能参数的计算

摘要

已经对人和动物心脏组织的机械性能进行了研究综述。根据已公开的数据，发现了一种近似函数形式，它取决于人心室的杨氏模量对变形量的依赖性。计算杨氏模量和其他弹性常数的平均值，并将其与已知的实验值进行比较。计算了两参数超弹性心肌Mooney-Rivlin模型的系数C ₁和C ₂。
