Stress relaxation test Abaqus
Stress relaxation test Abaqus
(OP)
Good morning, or good afternoon, depending on the side of the world you are in.
I am a student at TU Delft, and I am finding troubles when trying to handle Abaqus.
For a certain application, I am trying to perform a stress relaxation test on Abaqus, by applying a constant strain of 1 mm/min to a piece. The problem is that I cannot seem to find an option for doing so, and Abaqus documentation for my version (6.14-1) only shows terms related to material properties when I try to look for the information. After a long while and a long search, I am unsure whether it is possible to actually do such analysis, and I decided to ask to a reliable source.
Can such analysis be done in Abaqus?
Thank you in advance,
Guillermo Jiménez

RE: Stress relaxation test Abaqus
Now, to your question, assuming you are talking about a uniform 'simple' strain, all you need to do is specify a displacement BOUNDARY CONDITION of a specified magnitude/direction.
TU Delft is a good school with a strong team(s) in computational biomechanics. You should have plenty of support if you make a few friends.

Thank you very much for your support - you solved completely my doubt. And, indeed, I am new to FEM, and I will follow your advice.
Thank you again,
