Yes, I run it displacement controlled and use velocity with smooth step. NLGEOM is activated to take second order effect in consideration. Thank you for your tips about activating enhanced hourglass control an. I got a better curve. But now I have another problem. The new curve doesn't reach...

Hello, I am modelling a concrete column in ABAQUS and I don't understand the load deflection curve that I get. The curve reaches a maximum load, decreases and increases again. An image of the curve is attached. Can someone explain this behavior...

Thanks Mustaine3! I had problem with the units and I fixed it. I have also changed the Amplitude to Smooth Step and did other changes to the model as well. But still I don't get correct result. In the experiment the maximum load reached is 900 kN. However I only reach 90 kN before failure. I...

Yes You are right. The unit is meter. So there are no other mistakes in the model? I still don't get correct results like the experiment.

Hi everyone, I am a master student working on my master thesis using ABAQUS. I am modeling an experiment, but the problem is that my results from ABAQUS do not agree with the experimental results. Can you help me an check if I have done any mistakes? The model is a slender square concrete...
