This tutorial simulated a CEL explosion over a composite RC column with an X-shaped steel core in Abaqus. The concrete and steel X-shaped columns are modeled as three-dimensional solid parts. The steel reinforcements are modeled as wire parts, and the domain that contains explosive charge is modeled as an Eulerian ...

In this tutorial, the Simulation CEL explosion inside the RC UHPC building in Abaqus-Damage investigation has been done The Ulta-High-Performance-Concrete(UPHC) building is modeled as a three-dimensional solid part. The reinforcements are modeled as wire part. The TNT is shpere part inside the Eulerian domain. You can see figures of the ...

In this tutorial, the Simulation CEL explosion of steel-UHPC composite RC beam(column) with multiple encased steel profiles in Abaqus  has been done. The Ultra-High-Performance-Concrete is modeled as a three-dimensional solid part. The bar and strip are modeled as three-dimensional wire parts. The steel beam core and TNT part are modeled ...

In this tutorial, the Simulation CEL explosion in the depth of soil near a solid steel pipe in Abaqus  has been done. The Eulerian domain is modeled as a three-dimensional Eulerial part. The air, soil, and TNT are modeled as three-dimensional solid part. The steel pipe is model as a ...

In this tutorial, the Simulation CEL explosion over the composite panel(Concrete-Steel bar-Steel sheet) in Abaqus has been done. The concrete is modeled as three dimensional solid part. The TNT and steel sheet are modeled as a three-dimensional solid part. The steel bars are modeled as three-dimensional wire part. The Eulerian ...

In this tutorial, the Simulation Coupled Eulerian-Lagrangian Explosion over the Reinforced Concrete Beam in Abaqus has been investigated. Blast incidents in recent years showed that most of the terrorist attacks on public structures were explosions within short standoff distance. Reinforced concrete (RC) structures are widely used in civil engineering for ...

Tests of crater formation are appropriate tools to study the blast phenomena, the behavior and destructive power of different explosives and the response of soils and rocks under this type of load. The mechanism of crater formation is complex and it is related to the dynamic physical properties of air, ...

One of the major problems confronted by the designer of submersibles is to minimize the weight of the pressure hull for increasing the payload of a crew and necessary equipment and to simultaneously enhance the strength of the pressure hull for withstanding hydrostatical pressure, underwater explosive loading and other environmental ...

Reinforced concrete containment of nuclear power plant must be constructed and operated in order to protect the population and environment against an uncontrolled release of radioactivity in the event of severe internal or external accident occurrence, such as large fires, earthquakes, jet aircraft impact, that might be expected during the ...

An explosion on the ground surface can cause significant damage to a tunnel located at a shallow depth below groundA comprehensive approach to simulate the effects of an explosion occurring inside a buried infrastructure tunnel on the soil surface and on nearby tunnels is presented. The approach considers all the ...

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 ...

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 ...
