Simulation blast explosion over the composite column in Abaqus- Damage investigation

In this tutorial, the Simulation blast explosion over the composite column in Abaqus- Damage investigation – has been studied. The model contains three deformable parts. The outer steel box as a cover is modeled as a three-dimensional shell, the middle concrete is modeled as a three-dimensional solid part and the internal steel beam is modeled as a three-dimensional solid part. You can figures of the assembled parts at below

To model steel behavior under the blast load, elastic-plastic data with ductile damage criterion is used. The ductile damage criterion can predict the damage and failure of the steel part during the analysis. To model concrete behavior under the rapid load, Abaqus has many material models such as Brittle Cracking, Concrete Damaged Plasticity ….but in this simulation to observe the damage zone and its propagation, the material should be proper, so the input file or VUMAT subroutine can be useful. In this tutorial, concrete material data is used as an input file for Abaqus. The Abaqus explicit step is appropriate for this type of analysis. The contact between the concrete and steel parts is assumed as perfect of ideal contact. The surface to surface contact with contact property as tangential friction with shear stress limit can be used. The CONWEP method is used to model the explosion procedure. The two ends of the columns are fixed as weld joint. The nesh should be so fine, because of damage. The mesh has a strong effect on the form of the damage

After the simulation, all results such as damage variable, stress, strain, plastic strain, ….can be obtainable. You can see some figures of the results below
