Thank you! Actually, I was getting the spring stiffness wrong by a couple of order of magnitude!!

The analysis fail. It seems that the rotational degree of freedom was not involved. To test that I have try to modify it to 4, 5 or 6, but the analysis aborted anyways. Moreover, changing the load from a concentrated force to a prescribed displacement makes the beam rotate rigidly.. So it is...

Dear all, I have a quite simple problem but I cannot figure out how to solve it. I have a cantilever hollow square section beam made with S4 shell elements. At one end, I need to create a rotational spring for simulating a non-perfect encastre; I have created a RF and a coupling costraint to...

Hi Everyone, I am currently working with a Dynamic Implicit model and I'd like to stay with the implicit solver. However, when deformations and plastic zones starts being rather important, the Implicit solver tend to have difficulties and then it stops. I was then wondering if there is a way in...

Thanks @FEA way. Since I am not an expert Abaqus user (but that kind of internal constraints is like the basis for my models), could you please tell me how to do that? Or just upload an example file? (I have abaqus 2021)

Hi everyone, I am a structural engineer which is using ABAQUS mainly with truss or beam 1-D elements. I am having issues modeling a beam connecting two columns. The connection between the beam and the columns has to be a pinned one but columns need to be continuous. For being clear I am...

Hello, I am a structural engineer who is dealing with contact simulation for the first time and I am having some numerical issue. My model is made using steel beams and my aim is to evaluate how the structure collapse under certain loads. I have defined a contact using "Penalty" for both normal...
