2D contact problem

[Tinni1]

Hi,

I am trying to perform a 2D contact analysis in Abaqus standard following the example manual, getting started.
I have modeled a 2D deformable element in between 3 analytical rigid elements. I have established contact
After performing the analysis I see the deformable element does not bend or deform.

I have downloaded the python script from Abaqus documentation and ran it. There I can see the part deforms. I have cross-checked various parts between the model I developed and the Abaqus documentation model, but couldn't make out any difference.

Please find attached the screenshot of the deformed shape of my model and the model in Abaqus documentation.

Could anyone provide any direction, please?

First check if the displacement variable U is in the field output request.
Next check the contact normals at the contact faces. They have to point toward each other. In postprocessing: Options->Common->Normals->Show Normals-> On Surfaces

That’s the quasi-static forming example, right ? Clearly, contact between the rigid punch and deformable blank is not detected. Which type of contact do you use ? Double-check its definition. Also, which version of Abaqus is that ? Did you compare the input file of your example with the working one from the documentation ? Good text editors can make such comparisons automatically and highlight the differences.
