ADVNL 601, 106 for impact analysis?

Creator
Creator
Problem:
Wish to do an non linear analysis on an AISI 316 beam constrained at each end which is impacted by an aluminium "bullet" with a mass of 1kg and an impact velocity of 66 m/s. The displacement and forces in the beam resulting from this collision are the desired results from the analysis. This is an impact test.
This question might seem simple, but I am new to NX Nastran and I need to find the best and most correct approach to this analysis. Can I use ADVNL 601, 106 to achieve this? If so how do I set ut the problem? Is the method suggested in the following post a possibility? http://bbsnotes.ugs.com/vbulletin/showthread.php?t=27230 What is in this case meant by dynamic impact analysis? Is NX Nastran up to this kind of task?
Any tips are greatly appreciated! Thanks.

N/A

You can use SOL 601,106 for such a simulation. But you may also want to try SOL 701
which is an explicit solver that is well suited for impact simulation.
I have attached bulk data of a similar simulation of a ball impacting a plate. You
set up the simulation by placing the ball in a position just before impact and assign
intial velocities to the ball nodes. You would also want to make the object that
it impacts to be elastic-plastic material with a rupture load - so that when max
allowable strain is reached, the element is removed from the simulation.
