Simulation Blast response of aluminum/thermoplastic polyurethane sandwich panels in Abaqus

In this tutorial, the Simulation Blast response of aluminum/thermoplastic polyurethane sandwich panels in Abaqus has been investigated. The aluminum sheets are modeled as three-dimensional solid parts. The TPU is modeled as a three-dimensional solid 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. Polymers are increasingly used as core materials in sandwich structures and are popular due to their low cost, and relatively low density. Thermoplastic polyurethane is considered one of the most versatile plastic materials compared to regular rigid plastics

The aluminum material is model as an elastic-plastic material with Johnson-Cook damage behavior. The TPU is model as an elastic-plastic material with damage behavior. The dynamic explicit step with a mass scale to reduce the time of the simulation is selected. The perfect contact is assumed among the aluminum sheet surfaces to the TPU. The symmetry boundaries because of the symmetry conditions in the model are assigned to the parts. The CONWEP blast load procedure by defining the mass of the TNT and its location is used. The mesh should be fine to achieve the correct results

After the simulation, all results such as stress, strain, damage, failure, displacement, and … are available. You can see some figures for the results below

You can provide CAE, INP, and English video files of this simulation here. The cost of these files is Twenty-Six Euros. you can click on the bellow bottom to beginning the process
