Workshop: Simulation Eulerian Explosion Over Steel Pipeline In The Depth Of Soil In Abaqus

Existing studies on buried steel pipelines under explosion mainly focus on determining the safe distance at which the pipeline does not experience plastic deformation. However, intentional explosions can cause severe deformation in steel pipelines.

In this tutorial, an Eulerian explosion over a buried pipeline is simulated using Abaqus. The following models and equations are applied:

• JWL equation of state for TNT
• Us–Up relationship for air
• Johnson–Cook material model for steel
• Mohr–Coulomb plasticity for soil
