In this tutorial Simulation of hollow steel piles subjected to buried blast loading(CEL explosion) in Abaqus has done.A pile is a load bearing component of a structure that transfers the structural load to the hard soil or rock underground. The modern human civilization and smart infrastructure depend largely on the pile foundation for carrying its structural load because the pile foundation reduces the area of load distribution in the surroundings near the ground surface and thus, considered as a suitable foundation system in the regions with more congestion and a higher number of tall buildings. However, failure of a single pile can lead to disaster by causing progressive failure of the super-structure and the surrounding structures.In the recent decades, terrorist attack and bomb blast have caused failure of several structures. A small magnitude of the blast, if it happens in the close vicinity of one pile may lead to progressive failure of the whole structure.Moreover, the failure of the structure often starts from the soil because the soil is the weakest of all civil engineering materials. Hence, it is extremely necessary to understand the response of pile foundation in the soil when subjected to blast loading.You can see a figure about assembled parts at belo
In this simulation piles are modeled as three dimensional part with elastic plastic material couple with damage data,soil is modeled as three dimensional part with eulerian approach with elastic plastic behavior and TNT is modeled as sphere by JWL material method. Dynamic explicit step with general contact is appropriate for this type of analysis. After the simulation stress,strain and damage for piles, TNT wave,craters inside the soil and other result can be achievable .You can see some results of this simulation at below
