Bullet Impact on a Brittle Disk

[arun15]

Hi,
Can you please provide me with the source file for the simulation "Bullet Impact on a Brittle Disk"?

And can granoo be used to simulate planetary simulations, where velocities are upto 10-20 km/s and deformations are caused majorly by shockwaves?

Hello, sorry for the late reply, I was on holidays.

Hum, not sure, this is no more ballistic velocities (~1000 km/hours) but "hyperveloce" velocities ! From my knowledge, materials do not react as solid at these velocities. You probably must take a look on hydrocodes and/or sph methods. But, to be honest, this is quite far from my scientific topic, so I am not 100% sure...

Hi,
Thanks for the files. Well, indeed, materials do not react as solid at these velocities. Still, if we could just look at mechanical interactions during the impact, I assume we could gain some insights regarding the event.
