| 摘 要： | 建立了正交各向异性超弹性材料的本构方程来描述生物软组织的大变形过程,应用超弹性有限元方法对生物组织实验进行了数值模拟.通过计算结果与实验结果的对比可知与实验结果拟合较好,说明这种超弹性材料模型能够描述生物软组织的超弹性、大变形行为.

| Abstract: | In order to describe the large deformation process of biological parenchyma,the constitutive law for a sort of orthotropic-hyperelastic material is established.Basing on hyperelastic finite element method,numerical simulations of experiments are completed.Comparisons between experimental data with computational data confirm that this hyperelastic material could describe the large deformation and hyperelastic behavior of biological parenchyma. |
