What is Tunnel Stress Analysis with FEM about?

The document describes using finite element analysis to analyze stress and displacement in a tunnel wall. It includes: 1) Modeling a semi-circular tunnel as a solid element model in 3D space, applying material properties of concrete to the tunnel wall and constraints fixing its base. 2) Applying a vertical load of 10 GN to simulate the weight of the tunnel and solving the model to obtain nodal displacement and stress distributions. 3) Analyzing two proposed redesigns, Design A and B, that extend the en
