Cohesive Elements in Abaqus

Cohesive Elements in Abaqus

Cohesive Elements in Abaqus


I am studying a huge structure in which I use multiple cohesive elements "surfaces" to simulate glue. I created the by partitioning parts and then tied them to the second part they were attached to.
When I see the results of the job, the cohesive elements don't deform (no displacement) - they are white when I visualize the displacement output. I also get the following message "Results for the current deformed variable are not available for one or more nodes contained in the model. Deformations at such nodes are assumed to be zero."
Furthermore, I wrote on the INP file to print the displacements of a random (undeformed) cohesive element and the connecting parts and they returned with the same values.

Anyone has any idea on what might be causing this situation?
Thanks for the help.

RE: Cohesive Elements in Abaqus

Have you adjusted the coordinates of the nodes belonging to the adhesive layer to make them all lie in the same plane ? What about other output variables (stresses, STATUS) - are they displayed for cohesive elements ?

RE: Cohesive Elements in Abaqus

I haven't adjusted any coordinates, but I believe they are in the same plane already. I do obtain values for the stresses, but they don't very accurate. Also, Abaqus doesn't return SDEG outputs.
