Getting started with abaqus

[Tlaloc92]

I have a doubt about a simulation that I performed in abaqus. This model is a circular plate which is being pulled out by a bolt with a force of 100tonf, however I am not sure about the definition of the load. Looking at the load module, I have figured out that exists 2 ways to configure this force. The first one is with a surface traction along the hole where the bolt must be in, the second one is applying a pressure in the center of the plate where the hole drill will take place. Thanks in advance

 

[FEA way]

There are several ways to model bolted joints but if you don’t want to model the bolt itself (even as just 3 cylinders representing the head, shank and nut) then you can apply the load directly to the hole.

So, if I dont want to model the bold-plate interaction,I must apply only a tracion force along the inner suface.

The actual load distribution due to the presence of the bolt is more complex and theoretically you should mimic something like a bearing load. You could also use a coupling constraint to apply the load. Proper surface partitions around the hole might be necessary.
