Molecular dynamic simulation on Projectile
Hi, everyone~
Has anyone done MD simulation about projectile? Like a rigid body penetrating a thin target? I have recently heard that a group in Uni of southern california did such a simulation before. I will be appreciated if someone could afford me some information.
Thanks in advance.
Regards
Xu

Thank you~ But to my
Thank you~
But to my acknowledge, both Ansys Lsdyna and Lsdyna are used for FE simulation, not MD.
I am thinking about simulating the projectile processing using MD, which could used to compare with the FEM results.

Hello Xu,
I think this is the group that you were mentioning at USC:

Here is the paper which explains the molecular dynamics analysis of nanoindentation process of silicon nitride.
silicon nitride: a multi-million atom molecular dynamics study
P. Walsh, A. Omeltchenko, R. K. Kalia, A. Nakano, P. Vashishta, and S. Saini

Hello,Erkan: Thank you
Hello,Erkan:
Thank you for your information. It is a paper concerning with nanoindentation, which is a good work.
However, I think I didn't express my meaning exactly. I was trying to find out whether someone has done some work to simulation the penetration or percolation with MD.
Guess that a bullet runs into a thin film and comes out from another face, during which the film was broken with a hole in the middle of it. I thought that maybe in such a process, one could take the bullet as a rigid body and use MD to simulation the film, or vice vers, or simulate both of them using MD.
It is like a nanoindentation process, except that the velocity of the indentor is much more higher, it is like the 8th picture of this site:

Thank you again and sorry for my poor expressing.

MD simulation
Ls Dyna can also perform that see this website
