Blast incidents in recent years show that most of the terrorist attacks on public structures were explosions within short stand-off distances. In this context, columns are the most vulnerable structural components and their failure is the primary cause for progressive collapse in framed structures. On the other hand, many of ...

Far-Field UNDEX models must typically treat two UNDEX phenomena: shock loading and cavitation. Shock loading occurs as a result of the incident explosive shock wave impinging on the wet-surface of the ship structure. Cavitation occurs because the pressure in the surrounding water drops below its vapor pressure due to the ...

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 ...

Given the superior strength-to-weight ratio, stiffened panels have been used extensively in the main structure of ships and underwater vehicles. The loads acting on a stiffened panel in a ship is in-plane compression or tension, resulting from the overall hull-girder bending moment or torsion, shear force resulting from the hull-girder ...

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 ...

In this tutorial air blast explosion inside reinforcement concrete room in Abaqus has been investigated. The concrete room is modeled as three dimensional part with CDP material to predict compressive  and tensile damage. Reinforcement is used as beam part by wire element ans steel material. Dynamic explicit procedure is appropriate 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 , ...
