Simulation CEL explosion over the glass panel and damage investigation in Abaqus

In this tutorial, the Simulation CEL explosion over the glass panel and damage investigation in Abaqus has been done. The glass, air, and TNT are modeled as three-dimensional parts. The Eulerian domain is modeled as a three-dimensional Eulerian part. You can see a figure of the assembled parts at below

To model TNT behavior, the JWL equation of state is used. The Jones-Wilkens-Lee (or JWL) equation of state models the pressure generated by the release of chemical energy in an explosive. This model is implemented in a form referred to as a programmed burn, which means that the reaction and initiation of the explosive is not determined by shock in the material. Instead, the initiation time is determined by a geometric construction using the detonation wave speed and the distance of the material point from the detonation points. The air is modeled as Ideal gas with viscosity. To model glass behavior, Abaqus have some models which they are used in the different simulation. In this tutorial to consider glass damage and failure, the Holmquist model is used as an input file or VUMAT subroutine also can be used. The dynamic explicit procedure is appropriate for this type of analysis. The general contact algorithm with contact property is assigned in the interaction section. The fixed velocity and outflow boundaries are assigned to the Eulerian part. The volume fraction method is used to calculate the amount of TNT and air among the Eulerian domain to assign Eulerian material. The mesh, especially for glass panel and Eulerian domain, should be so fine to reflect a good result

After the simulation, all results such as damage, failure, stress, strain, TNT wave propagation, TNT pressure, and ….can be achievable. You can see some figures for the results below
