Simulation Couple Eulerian Lagrangian explosion over RC column with steel beam core in Abaqus

In this tutorial Simulation Couple Eulerian Lagrangian explosion over RC column with steel beam core in Abaqus has been studied. The concrete column and steel beam are modeled as three dimensional part,the domain is modeled as eulerian part with TNT and the bars are modeled as three dimensional wire part which you can see figures of the assembled parts at below

  Steel material with elastic plastic behavior depend on strain rate couple with ductile and shear damage criterion has been used. To model TNT behavior JWL equation of state by considering detonation point.This model can convert chemical energy released from explosion phenomenon to mechanical pressure.The concrete is modeled as a brittle material with Johnson Holmquist which can be achievable in inp file or vumat subroutine. Dynamic explicit step which used for this simulation. The contact between concrete and steel beam is considered as perfect contact and the bars is used as a embedded region inside the concrete host. General contact procedure to consider interaction among all part with contact property is applied. The boundary conditions such as fixed and zero velocity are used for composite column and eulerian domain. To use eulerian material abaqus gives two way, the first is volume fraction and the second is uniform material . In this tutorial to define the location and amount of TNT volume fraction method is used. The mesh should be so fine to get accurate result

After the simulation all result such as concrete damage variables, ductile and shear damage,stress,strain….can be achievable .You can see some figures of the result s at below
