Simulation Eulerian explosion in the Lagrangian pipe in Abaqus

This file contain CAE and full English video of Eulerian explosion in the Lagrangian pipe in ABAQUS step by step.An explosive detonated in water is a rapid chemical reaction in a substance, which instantly converts the original material into hot explosion gas with a temperature of approximately 3000C and induces a shock pressure of up to 5000 MPa transmitted to the surrounding water and propagating away from the source. In underwater explosion, the peak overpres-sure is of several orders of magnitude greater than the hydrostatic pressure. Therefore, the hydrostatic pressure is ignored and the peak overpressure is simply called as peak pressure. The pressure history of the shock wave at a given point starts with an instantaneous pressure increase to a peak pressure, followed by a decaying exponential function

TNT and Air has modeled as a eulerian parts and pipe as a lagrangian part. for modeling TNT behavior JWL equation of state and for the air Us-Up has been used. For predicting damage in the pipe appropriate model has been used. During the analysis pipe failed and TNT pressure destroyed the pipe wall.You can see some picture of this analysis bellow
