Radial and Hoop Stress

The below post is related to an archived discussion

Hello:

In reference to one of the earlier discussions, I used solid.srr to plot radial stress around a cylindrical hole (in a cubical block). Unfortunately, I am getting an error message (attached please see the screenshot) when I try to plot the radial stress around the hole.

I am not sure what I have missed here and look forward to hearing your comments.

I would also appreciate if you would explain the difference between solid.srr and solid.sl11

Thanks, Shashank
