THE *FAIL STRESS OPTION CAN ONLY BE USED WITH PLANE STRESS ELEMENTS?
(OP)
I got this error in my simulation:
"THE *FAIL STRESS OPTION CAN ONLY BE USED WITH PLANE STRESS ELEMENTS"
I tried looking at the manual , but couldn't figured out how to overcome this problem.
Any suggestions?
Thanks in advance

You are probably using continuum solid elements (C3D8R) with solid sections. To use the composite failure criteria in Abaqus, you must use continuum shell elements (SC8R) with shell sections.
Hope this helps

When I use 3D solid continnuum element, no distortion takes place and the jobs runs until the it is completed.
This happened as I was making the mesh finer. Any Ideas?
Thanks

Are you modeling progressive damage using the Hashin failure criterion? Do you have nonlinear geometry turned on (NLGEOM=YES) in *STEP card? Both of these things could be causing element distortion errors. You may not be seeing it for 3D solids because you are not modeling damage...?

Excessive incremental rotation of the elements in element set ErrElemExcessIncrementalRotation-Step1.
There is only one element with excessive rotations
The NLGEOM is always on :). I have included a picture of the last frame before the analysis is aborted.
My wild guess is that as the mesh is made finer, the contact force increases hence more distortion.
Thanks for your help :)

I love your blog by the way, It has something informative, easy to follow posts.

Node on structural elements such as shell elements not only have translational but also rotational degrees of freedom. If you do not restrain DOFs appropriately, you'll end up encountering unexpected issues.

Apologies for the late reply, my laptop broke and i had no means of replying.
RE: THE *FAIL STRESS OPTION CAN ONLY BE USED WITH PLANE STRESS ELEMENTS?
I have wanted to make that clear, just in case some else in future experiences similar error.
