I am doing a buckling simulation and I can't seem to do the pin connection correctly. I have a cylindrical model under compression load, I've tried putting "displacement" support but I don't know which component should be zero. Please help.
Thank you very much for the help! I'm not sure if I.'m doing it correctly though. I used remote displacement and promote it to remote point. On the remote point, I selected the top face of the model.
I then applied the force onto the remote point (which I made into a named selection), and got this result. I'm not sure if this is what it should look like.
Thank you very much! You are a big help!
Hi, I'm still having problems regarding the result of the simulation. Comparing the buckling critical load I got from the simulation and the one I calculated, there is a 20% error in their values. I'm not sure if I have done something wrong in doing the remote displacement support or the force application.
The equation you used for the hand calculation might have simplifying assumptions built-in, such as Euler beam theory, while the ANSYS model is not using the same simplifying assumptions. The agreement of 20% is adequate to show that you have not made any significant mistake such as using the wrong units in a material property, for example, which could result in an order of magnitude error.
