1)Can someone share the .inp or cae file of the technology brief 

2) when I simulate, the velocity tracking of the projectile shows a constant velocity in a certain time duration of its travel, which is not physically possible. (attached image)

this means there is a contact or interaction loss. I am using general contact.

3) when simulating a projectile impact on a composite laminate. can someone guide me with a correct interaction type and how to implement that?

right now I create a lamina, I pattern it and merge lamina to create laminate by retaining boundaries. is this the right way to create a laminate? I am using a rigid projectile and assigning a remote point (RP) and applying velocity and BC to RP, adding inertia to RP.

can anyone suggest me a  tutorial or course to learn ballistic simulation on a composite laminate target?
