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 ...

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 ...

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 ...

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 ...
ادامه نوشته »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 ...

In this video CEL explosion inside concrete tunnel in interaction with soil in ABAQUS has been investigated.To perform this analysis Volume Fraction technique to extract TNT amount has been used. Concrete tunnel modeled as a there dimensional with JC material for better performance in explosion phenomenon.Air modeled as Ideal gas , ...
ادامه نوشته »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 ...
