Hi,
I have been trying to model the 1D elastic bar problem outlined in the link below using Abaqus:
Link

1) I have never done Dynamic analysis apart from a few tutorial so I am slightly confused on whether I need to do an Explicit or Modal analysis, or else?
2) I have managed to get the displacement response results as in the link, but am not able to get the stress profiles.
3) To give it the 1D effect, I have constrained the lateral movements in the bar.

I would appreciate some urgent hints and guidance.
