“Numerical Simulation Data on Stress Distribution and Displacement in Tunnel Excavation Using COMSOL Multiphysics”

The datasets generated and analyzed during the current study were obtained from numerical simulations performed in COMSOL Multiphysics® [version 6.2]. The raw simulation files (.mph), processed tabular data (.csv), and visualization outputs (.png, .jpgSupporting the findings of this study are available from the corresponding author upon reasonable request. The tabular data include Von Mises stress distributions before and after excavation, as well as surface displacement profiles extracted along the tunnel axis. Figures presented in the manuscript were produced directly from these datasets. Since the simulation files are large in size ( around 5MB), they are not hosted publicly but can be shared upon request.
