Simulation sequential air blast explosion over the concrete slab reinforced with CFRP sheet in Abaqus

In this tutorial, the Simulation sequential air blast explosion over the concrete slab reinforced with CFRP sheet in Abaqus has been studied. The concrete slab is modeled as a three-dimensional solid part. The CFRP sheet is modeled as a three-dimensional shell part. You can see figures of the assembled parts below

The Concrete Damaged Plasticity material model is used to model concrete slab behavior under severe blast load. This model can show the tensile and compression damage during detonation. The lamina elasticity and Hashin’s damage criterion with damage evolution is used to model CFRP behavior. The sequential analysis as three separate dynamic explicit procedure is done. In the first simulation, a dynamic explicit step is used. The ideal contact is selected between slab and CFRP. The CONWEP air blast procedure is used to demonstrate the blast wave effect over the reinforced slab. The fixed boundary condition is used for the sides of the slab. The mesh should be fine to achieve the correct results.

After the first simulation, all results such as stress, strain, tensile and compression damage, and … are achievable. Now, these results should be imported to the new simulation as an initial situation. In this way, the slab and CFRP have initial residual stress and damage and the second detonation is applied to the damaged parts. At the end of the second simulation, again all results are obtainable. In the third simulation, the results from the second simulation are considered as the initial conditions.

You can see some figures for the results below
