This research employs advanced numerical analysis using the Coupled Eulerian-Lagrangian Finite-Element method to evaluate the blast resistance of an underground steel pipeline subjected to surface and subsurface detonations. A pipeline model, reflecting standard gas and oil infrastructure, was created in Abaqus with a 1-meter external diameter, 10-millimeter wall thickness, and 12-meter length, buried 2 meters deep in brown clayey soil. The study applies various constitutive models, including Simplified Johnson-Cook Plasticity for the pipeline, Jones-Wilkins-Lee EOS for TNT, ideal gas EOS for air, and Mohr-Coulomb Plasticity for the soil. Results reveal that subsurface explosions severely compromise the pipeline's structural integrity, causing concentrated stress and displacement, while surface explosions produce broader, less severe effects. The study highlights the need for further research on the impact of water on pipeline resilience in different environments.
