Landmine (IED) Blast Simulation

We undertook this baseline analysis to demonstrate the accuracy of our landmine blast simulation.

Here we are showing our simulation of a physical test that was conducted at The Defence Science And Technology Laboratory (Dstl), Porton Down, UK We have a 1kg explosive charge buried in soil (Leighton Buzzard 14/25 sand) at a depth of 50mm. Set at a 150mm offset from the soil we have a 12mm ARMOX 440T plate, mounted into Dstl’s standard test rig.

The images to the left show the deformation of the ARMOX 440T plate combined with a representation of impact material with a density greater than air (left top image) and a greater than 0.1% volume fraction of explosive (left lower image).

The graph shows how our simulation correlates extremely well with the actual test results.

The image to the lower right shows the deflection of the ARMOX 440T in a section through the test piece and test rig.

At Design and Analysis Ltd. we are working on vehicle protection systems to mitigate landmine or Improvised Explosive Device (IED) blasts to save lives.

In addition to the standard armour plating solutions we are developing lighter weight composite solutions for future vehicles.
