I tried running a bolted joint analysis to test out if there’s uniform pressure around the edges of two plates joined by two bolts. I had a lot of failed results, so I thought that’s a reason for net getting any results related to Von Mises stress or any other strains. But even after successful analysis, I don’t get the required field output, except for displacement and forces.
What should I do to view other results…? I’m new to this software and analysis in general.
Can you share the .pmx file (upload it to some hosting website and paste the link here) ?
This drive link contains the .pmx file
You have to set access to “Anyone with the link” before copying the link.
This is the updated link.
The analysis struggles to converge. Check the tutorials about bolt pre-tension:
You should have two parts for each bolt, add a boundary layer between them and apply the pre-tension there. It’s also good to use more tie constraints and boundary conditions (maybe even displacement-controlled pretension) initially to avoid rigid body motions and then try to relax them a bit.
Thank You. I’m running the analysis right now. Also, is there a way to reduce the number of iterations in a single ATT?
You can use the *CONTROLS keyword (add it via Keyword Editor) but it’s not recommended in most cases.
I followed through the vid and your comments. But this is what I got.
What is the error here?
Could you please suggest me the proper method to get the Von-mises stress…
I want to find out if there is uniform pressure between the two members for placing a gasket for sealing against water and dust.
The bolts should be compound parts consisting of 2 segments each. Apart from that, refine the mesh significantly, remove contact from where tie constraints are and try with tied contact for now (defined by just changing the surface interaction property type to Tied). Also, reduce the initial increment size to 0.1.
Not in the Search Contact Pairs tool, find Surface Interactions in the model tree and edit Surface_Interaction-1.
