The aim of this study is to investigate the hyperelastic material models to describe the non-linear stress-strain behavior of tracheal smooth muscle tissue. Specifically, the goal is to validate the material model with experimental data using different finite element models and discuss the trends in stress-strain behavior of smooth muscle tissue. Both 2D and 3D finite element analyses were carried out to estimate the stress-strain behavior of the smooth muscle tissue. The results obtained indicate that the developed Ogden material model is valid and useful in explaining the stress strain behavior of tracheal smooth muscle tissue under different conditions. Finite element simulation results of the stress-strain behavior in the transverse direction are presented.
本研究的目的是研究超弹性材料模型，以描述气管平滑肌组织的非线性应力-应变行为。具体而言，目标是使用不同的有限元模型，通过实验数据验证材料模型，并讨论平滑肌组织应力-应变行为的趋势。进行了二维和三维有限元分析，以估计平滑肌组织的应力-应变行为。所得结果表明，所开发的奥格登材料模型在解释不同条件下气管平滑肌组织的应力应变行为方面是有效且有用的。给出了横向应力-应变行为的有限元模拟结果。
