Great tutorial! However, I have a problem with the result. I did everything like you but as a result my plate mesh does not break off and flies with the bullet. The plate deformation is small and the mesh just disappears. Do you know how to change it?
Probably the plate is behind the bullet. In the visualitation, try to take out the bullet and see only the plate. it is not like the videos but you can check that the plate doesnt desapear
how do I take the measurement in microseconds?... I think iam not in the right time scale. If iam keeping te time at 0.1 sec iam getting some result. But at hte same time if iam keeping time in microseconds(20*10^-6), there is no result. Kindly help...
He gives the inertia because he defines the bullet as non deformable (discrete rigid), so no material can be asigned to the bullet. So you wont define a density for the bullet so it wont have mass. In order to "solve" this problem you just asign a moment of inertia and is kind of fixed.
@@fertrueba96 why is he giving BC to the reference point and fix its dofs except Z-translational, i mean i would just assign initial velocity in the Z direction and thats all, i dont understand the BC for the bullet part.
@@outplayed4511 I am not completely sure, but the BC part is to indicate the bullet to just go along Z direction. This w means the bullet CAN NOT rotate. And is assigned to the Ref. point because that where u have the moment of inertia (which represent the whole bullet). To be said, I think is not 100% accurate to do it like that as it might affect the deformation of the bullet afterwards. The easiest way to solve this question is to run 2 simulations, one with that BC and one without the BC and see the differences in the results.
Great work! could you add voice next time on subsequent tutorials please? I will give you 5 star over and over again if I have the chance! Regards
Thank you Sir. Could you please make one video on Road Tunnel. I need help with blast analysis on the tunnel.
I really like the videos from this channel but why is there no sound/voice?
Great Jon👏

change in properties ductile displacement to 0.001
I'm facing the exact same problem
@@srijanbansal6078can you suggest any way to find displacement at failure value in damage evolution
What is one square in the grid equal to and why exactly this approximate size??
Could you see the velocity after impact any diffrence in bullet velocity
Can you model the bom or the TNT in abaqus
What parameters should we consider from ballistic test for the final result
How much time does it take for the simulation to finish?
Why is bullet part created as shell but not solid?
Is there other option if extended tools are not working
How many nodes did this simulation use? was thinking if it can be done in student edition
Is it possible to replace the bullet with an
rectangular shape ?
Yes
can you learn me how to simulate impact load on a slab reiforced with CFRP ? even if it is not for free

I too am confronted with this problem and if you have the response please share it and thank you
Can we get final analysis pdf report as same we get with ansys software
Why giving inertia to bullett?
