In this tutorial, the Simulation air blast over a composite panel( Glass Epoxy-Ceramic-thermoplastic polyurethane) in Abaqus has been done. The epoxy glass composite part is modeled as a three-dimensional shell part with sixteen layers. The ceramic and polyurethane are modeled as three-dimensionalsolid part. You can see a figure of the assembled parts below
History presents evidence of the risk and repercussions of explosions to both structural integrity and consequently human life. Due to this, a great deal of effort has been expended by the engineering community as well as government agencies to improve the impact and shock resistance of engineering structures. Several studies have been carried out on the development of sandwich structures that are able to withstand high-intensity impulse loading
Numerous criteria have been presented on the degradation of composites laminates so far, which stems from the difference in the material properties and manufacturing methods. However, some of these criteria are commonly used and have shown good accuracy in studying the behavior of composite laminates. Also, in this study, Hashin’s theory is used
To model TPU material, the elastic-isotropic plasticity with ductile damage criterion is selected. To model ceramic behavior, the shear modulus with drucker prager hardening couple with equation of state and ductile damage
The dynamic explicit step is so proper for this type of analysis. The CONWEP air blast method is selected, in this way the mass and location of the TNT should be defined. The ideal contact is considered for the interaction surfaces. The proper boundary conditions are assigned to the sides of the panel. The mesh should be fine to obtain the correct results
After the simulation, all results such as stress, strain, damage, failure, fiber damage,… are available. You can see some figure for the results below
