tie-Contact problems with Abaqus
tie-Contact problems with Abaqus
(OP)
Hello guys,
I am new on Abaqus and I have a problem with one of my project. I made an assembly with solid and two shelled cylinders.
I apply a pressure on the shelled cylinders. I tied the cylinders to the solids with the tool constraints (pic bellow)

I have a problem when I start the analysis, there are errors that you can see with the next pic:

I really don't know if it comes from the tie or something else...
Thx you for your interest
Best regards,
Dankoon

RE: tie-Contact problems with Abaqus
2. You should connect the shells to the solids with Shell-to-Solid-Coupling (Constraint in Interaction-Module). And you should create a separate constraint for each of your 4 connections.

Sorry I didn't post the screenshot of the errors. It's the next picture I have an error with my material..
I read that I have to assign a local orientation in the material tool, should I do this for all the models?
Thx

RE: tie-Contact problems with Abaqus
In the Property Module go to Assign>>Material Orientation
There still could be issues with your constraints but you need to tackle this first. If you can't figure out which elements are having this issue you can usually open up the .odb and under element sets CAE creates a set called something like error_no_mat_orientation.

I don't know if it can help you.. I wonder on what I have to add an orientation...Sorry for my lack of knowledge I'm learning this alone..
Thx for your answers by the way!

In the Property Module go to Assign>>Material Orientation
Then follow the on screen commands to select which direction you want the material to be oriented. Then little triads will be placed on the model indicating the material orientation. Again this has to be done everywhere an anisotropic material is assigned.
I would also suggest making a copy of the model with the material being isotropic so that you can work on solving your tie-constraint problem while also working on the material orientation problem.
