Simulation air blast explosion over the rubberized concrete column reinforced with green composite in Abaqus

In this tutorial, the Simulation air blast explosion over the rebberized concrete column reinforced with green composite in Abaqus has been done. The rubberized concrete column is modeled as a three-dimensional solid part. The green composite with some layers is modeled as a three-dimensional shell part. The steel reinforcements are modeled as wire parts. You can see a figure of the assembled parts below

Reinforced concrete (RC) is a widely used construction material and its structural behaviour under static loads is well established. However, load bearing elements can also be subjected to more unconventional loads e.g. from blast pressures originating from explosions. This topic has received increased attention over the past decades. The discussion typically relates to either unintentional causes such as gas explosions; to malicious threats like global terrorism (improvised explosive devices), or to surviving bomb blasts in shelters in conflict zones. Regardless of the intent, explosions can cause considerable damage and loss of life. The rubber waste additives in RC act as an absorber and balance all internal stresses in concrete

The Concrete Damaged Plasticity is used to model the rubberized concrete column under the blast load. The laminal elasticity with Hashin damage criterion is selected to demonstrate the composite behavior under severe load. The elastic-plastic model is consider for the steel reinforcement. Because of the rapid deformation and massive detonation load, the dynamic explicit step is selected. The Tie constiraint between green composite and concrete, , and the embedded region contraint for the steel reinforcements are used. The CONWEP air blast load with specific amount of the TNT in the near distance of the column is selected. The boundary conditions is applied to the two ends of the cmloumn. The mesh should be fine to get the proper results

After the simulation, all results such as stress, strain, damage, failure, force, displacement, and … are available. You can see some figures for the results below
