ٍSimulation buried steel pipelines against Eulerian-Lagrangian subsurface explosion in ABAQUS

Buried pipelines are among the most important elements of lifelines used for distribution of water, gas, oil, etc. Buried pres-surized gas pipelines are likely to be endangered by accidental explosions in process industries, explosives factories, open pit mines, quarries, public works or even intentional explosions near a pipeline Multiple explosions ...

Simulation progressive failure in reinforcement concrete structure under eulerian explosion in Abaqus

The progressive collapse of structures under blast loading has attracted great attention all over theworld. Some guidelines give specific procedures to analyse the progressive collapse of building structures.Progressive collapse refers to the failure of one or a group of key structure load-carrying members that gives rise to a more widespread ...

Simulation air blast explosion over concrete frame in Abaqus

A growing number of terror attacks all over the world have become a threat to the human civilization.In the last two decades, bomb blasts in crowded business areas, underground railway stations, and busy roads have taken numerous lives and destroyed properties in different parts of the world. However, blast response ...

Assessment of damage to an underground box tunnel by a surface explosion in ABAQUS

Recently, external terrorist activities have become one of the most influential events on tunnel structure safety because of the absence of proper mechanisms to detect these events in time to take preventive action. The present simulation used ABAQUS software to investigate the  behaviour of an underground box frame tunnel caused ...

Simulation Eulerian Explosion over Steel Pipeline in the depth of Soil in Abaqus

Existing studies on the response of buried steel pipelines to explosion generally concern finding safe distance of explosion where pipeline does not undergo plastic deformation while intentional explosions impose intense deformations on steel pipelines. In the present video Eulerian explosion over pipeline has been simulated. JWL equation of state for ...

Simulation Eulerian Explosion over Concrete Wall in Abaqus

In this tutorial simulation CEL( Couple EulerianLagrangian) explosion over the concrete wall has been investigated. .TNT and Air are modeled as a Eulerian parts and Concrete as a Lagrangian part. To model TNT behavior JWL equation of state and to model air behavior Us-Up equation has been used. The JWL ...
