Abaqus Tutorial: Modelling and simulation of compression test of mild steel Using Abaqus

[@eltonsandoval3764]

Thank you very much for this video you are my hero, you just saved me from failing at the university.

Hi First of all, I would like to thank you for the effort you put into making this video. Secondly, I have a question and I wish you have the answer to it. I wanted to do a compression test on a "bucky ball" (and more precisely on the pentagon side which means 5 spheres where I cut a little bit of material in solidworks so that I can put a discrit rigid with contact interaction). But the problem is it doesn't work unfortunately. On the monitor window, it says that there are some surfaces that abaqus doesn't recognize. And when I add a constraint (coupling), it actually works but the bucky ball run far away from the two rigid solids. And that is not real at all knowing that there is only a Z-displacement (U3). Can you please help me ? I WOULD BE VERY GRATEFUL. Thank you

It shows "My learning edition restricted to 1000 nodes" while data check. What can i do now pls give some suggestions

Increase mesh size, use coarse mesh

Each time I try to define the couplings on the top surface of the Rob i get the Error : SURFACE ASSEMBLY__PICKEDSURF13 CANNOT BE A RIGID SURFACE WHEN USED IN THE *COUPLING DEFINITION IN Abaqus/Standard. (What to do in this case.)

I have the same error, did you find a solution?

[@sameterkan3892]

delete coupling, it is not need. Because of this the part rigid.

How to do failure in compression just like you show in tension

You can use properties of failure of your material as Johnson Cook damage material model.
