Good evening fellow colleagues,
I am working with abaqus python scripts and having a serious trouble with entities selecting. One particular example is selectig all the faces in a certain region where z=0.
I am using the "findat" function, but I only know how to specify a direct coordinate, not...
Good Morning fellow colleagues,
I am trying to run a quasi-static analysis using ABAQUS Explicit. My model consists in a Polymer Cylinder clamped on one end and compressed on the other.
Because of my material properties, I have to impose a controled displacement of 6 mm/min until it reaches 80...
Aisling,
Since you are using solid elements, the general contact should work fine. I guess your problem is with the user defined material. I am not used to work with subroutines, so I can't help you much.
My suggestion is:
If you modified another subroutine to do yours, you should run the...
Bartosz,
Thanks to your tip, I was able to find some interesting information in the Abaqus manual.
"The terminology “contact edges” refers to feature edges of surface facets (on both shells and solids) as well as to segments representing beam and truss elements. The contact edges representing...
Hi Aisling,
I found a temporary solution for my problem, but its not really what I wanted. I put a small gap between the contact parts and the model runs fine.
I have a few questions for you, regarding your problem:
Have you tried the following combinations?
-User defined material with...
Firstly, thanks for you reply Bartosz!
Its not only the warning message, but I saw the parts passing through each other in the results. I suspect the reason for that is the initial condition of the two bodies (initially bonded). When I put a small gap between them, the contact works fine.
I...
Good Afternoon fellow colleagues
Recently, I've been running a few tests with contacts in abaqus. The last one (a beam-solid contact) failed. It is basically a polymer pipe with four wires of helicoidal tensile armor inside. The contact seems to be ignoring the polymer layer and the wires are...
Okay, that didn't help much. I was able to solve this problem myself switching the step increment to "auto". I guess the previous increment was a little high.
Now, I am trying to make several beam-beam contacts inside a plastic structure. Still using general contact. But now the problem is the...
Good afternoon fellow colleagues,
I am running a few contact tests in ABAQUS. One of them is a beam-beam contact. Doing a little research, I saw that the explicit general contact was the only way to do that. When I tried that, the beams seem to pass through each other. Does anyone happen to...
Good evening fellow colleagues. I am trying to do a stress concentration analisys at the corner of a beam structure (see attachment). I am trying to use MPCs to connect the beam element tip with the shell mesh, but when I check the analysis, I get an error message saying that my elements are...
I tried "Parabolic", but didn't change much. I'm calling the day. Tomorrow I continue. I appreciate all the help you gave me till now.
Good evening to you
