title: Non-linear material models for tracheal smooth muscle tissue.
abstract: 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.
