Simulation internal explosion inside the aluminum pipe reinforced with epoxy glue and steel cover in Abaqus

In this tutorial, the Simulation internal explosion inside the aluminum pipe reinforced with epoxy glue and steel cover in Abaqus has been studied. The aluminum, epoxy, and steel cover are modeled as three-dimensional solid parts. You can see a figure of the assembled parts below

The aluminum material is used for the internal pipe with elastic and Johnson-Cook plasticity behavior. To predict the damage and failure during the blast load, Johson-Cook damage is considered for the aluminum pipe. The epoxy material is used to model adhesive material between two metal pipe and for that, traction elasticity with damage data for the traction-separation law is implied. The steel material with elastic-plastic behavior couple with ductile and shear damage is selected for the external metal cover. The dynamic explicit procedure is appropriate for this type of analysis. The perfect or ideal contact is assumed between adhesive and steel, adhesive and aluminum pipe. The CONWEP blast load procedure is used to model the blast load over the internal surface of the aluminum part. The source point for the TNT is assumed at the center of the aluminum pipe with one Kg mass. The fixed boundary condition is considered for the two sides of the internal pipe. The should be fine to have better results

After the simulation, all results such as stress, strain, damage, …are obtainable. The aluminum pipe and adhesive material are completely damaged, but the steel cover has remained without damage. You can see some figures for the results below
