Hi guys.
Do you think it is possible to simulate ballistic impact and material resistance with Rhino/Grasshopper plugin?
I need to specify and simulate:
Missed the Impact word and was going to talk about ballistics… Impact, like a water bubble wave? Depends on the target’s material… Ballistics added… Doable in GH but complicated!
No, that’s what 6 figure FEA packages are for
Could be built gradually - It’s a ballistic module + a material deformation matrix plus a collision, dispersion matrix. How hard can it be?
Hi guys, thanks for your replies.
What about “Intact.Simulation for Rhino Grasshopper 8” ?
Do you think would be helping ?
Best.
Hello
I was on this on my previous job and most of tools were Fortran or C. Also they had not a lot of users they were quite hard to validate. Materials models and parameters were very important. Calculations time were quite long …
So I think the best way is surely to make some tools in Grasshopper to make the inputs and some others to analyse the outputs. And use existing tools Ls Dyna Ouranos… you can ask Thiot engineering they do this kind of simulation
PS i developped a complete tool for 6dof 5dof ballistic simulation tool for unguided objects in and out the atmosphere. I used RhinoCommon and rhino3dmio. But a similation was faster than reality. But for impact I think it is far far slower 1ms equal many hours!!!
I use Unreal but it’s for vis only, they have ballistics plugins from Niagara and chaos. I use for games and cinematics don’t know if it’s useful for real world applications though. But they do have real-time physics simulation. Currently I attached a rocket thruster to a chair with a model typing and it works and is really funny to see that just the typing movements interact with the sim causing the model to either take off or crash.
Or you could try Houdini I think they have a free version.

Hi, thanks for the suggestion: I’ll take a look.
Hi Laurent, nice to meet you !
I’ve used your Nautilus plugin a few times…
Thanks for your help: I ​​will contact Thiot Ingenierie.
What about your 6dof 5dof ballistic simulation tool ?
Can you explain it better, thanks.
Best regards
6dof tool like that
I was quite happy with mine it has many gravity model many atmospheric model
It allowed the use of near real time wind
Quite all data could be stochastic with gaussian or uniform models
Alls inputs data had an unit.
It was able to generate latex document
5dof for sounding rocket means no roll so could have fast calculation with adaptative Runge kutta
Hi Laurient,
good morning and thank you for your reply.
I will check it and let you know.
Kind regards
Also to add some clarity there are many domains in ballistics
Internal ballistics When the shell is inside the gun tube barrel
External ballistics Shell or object is in the air
Terminal ballistic when the object impacts something . It seems you are just interested in th last.
In France you can learn these subjects in Ensta Brest ( they surely have some master now)
There is also some introduction in Eurosae

It is in French but could be possible to have it in english if enough people ask for it. I give a 1hour lecture once a year
Hi Laurent, yes, in this case we just need to simulate the impact of the bullet.
Thanks.
