Collimatrix Posted May 4, 2021 Report Share Posted May 4, 2021 I've noticed a lot of ballistics FEA simulations popping up on Youtube lately. A result of the ever-dropping price of number-crunching power? Who knows. I cannot, of course, vouch for the accuracy of these simulations. They sure are pretty to look at though.

System is still in development. During first testing stage recently they managed to destroy launcher unit, heh. Beer and SH_MM 2 Quote Link to comment Share on other sites More sharing options...
Collimatrix Posted May 17, 2021 Author Report Share Posted May 17, 2021 The numbers he's getting for that test though; ~50% reduction with a large and variable amount of fragments, are in line with other estimates I'd seen published of APS vs APFSDS.

It's not that difficult to get the simulation to show whatever you want to show. Quote Link to comment Share on other sites More sharing options...

It's not that difficult to get the simulation to show whatever you want to show. One thing that I think it could be useful for is to conduct comparative experiments. For instance: I'd like to see an experiment where a simulated HEAT jet or APFSDS projectile is shot at a semi-infinite target with an ERA array in front of it. You'd test once against the target, once against the reference array and then against experimental arrays with different materials (HHA, aluminium, titanium, composites etc.). So long as the targets have the same composition and dynamics, and the relevant factors (density, yield strength, modulus of elasticity, hardness) are correctly reproduced, you should be able to draw useful inferences about relative ME and TE of different array designs from a materials standpoint.

Vicious_CB Posted May 23, 2021 Report Share Posted May 23, 2021 Here is another good one: Abrams upper glacis test. Dejmian XYZ6 days ago (edited) I wanted to present plans for the future, but I will present plans for the next simulations. I would like to simulate the armor of the Abrams again, as I read somewhere that the thickness of the glacis was increased in later versions, but now I'm not sure. So if anyone has good source it would be helpful. If not, I will do it for 38mm, but with a side angle, so that the total inclination is 83-84 degrees. I would also like to do one simulation at low projectile speed to test the ricochet. One of the slower APFSDS is the OFL-90-F1 (1275m / s). Also it looks like hes looking for info for another Abrams test. AFAIK the upper glacis thickness was never changed from the original 38mm plate.

There is so much that is unknown about ballistic science, armor construction, and projectile construction that these are mainly to show how a projectile armor interaction maybe, might, possibly, perhaps, somewhat, workout in perfect circumstances. These videos are pretty much for entertainment purposes only. Quote Link to comment Share on other sites More sharing options...
