Trachea Analysis Problem Specification
This tutorial shows how to simulate deformation of a trachea under a pressure load. Dimensions and properties used in this tutorial are:
- 7 cartilage rings, each 300 degrees, thickness 1.1mm, width 5 mm, E = 2 MPa, Poisson's ratio = .3
- Tissue thickness 1 mm, width 10 mm, E = 20 kPa, Poisson's ratio = .3
- Trachea diameter of 20 mm
Steps to modify properties (to model tracheomalacia) and geometry (to model tracheotomy) are shown in the exercises.
Below is a summary of Ansys steps demonstrated in the videos:
