A simple tutorial on how to use bolt pretension to clamp two parts together before applying a force to pull them apart. The attached file is an ANSYS 18.2 archive.

Here is a followup video showing how to do a beam connection. This takes a little less effort than the solid fastener shown above.  The attached file is from ANSYS 2019 R3.

Here is a third model in the series that shows using midsurface bodies and shell elements to do the same thing as above on a slightly more complicated joint.  Thanks to Aren for the geometry.

Dear peteroznewman,

How can I apply  bolt pretension to clamp two parts together in ANSYS V16.0 (I´m using beam element to emulate a 3D bolt).

Thank for you time.

 

Rebeca.

Dear Rebeca,

I don't recall what ANSYS V16 looks like.  Is Bolt Pretension listed in the Loads in Workbench?  Please insert a screen snapshot of the available loads.

Dear peteroznewman,

here you are, I have the option to insert BOLT PRETENSION in static structural but it does not display nothing on named selection.

Dear peteroznewman,

here you are, these are the load available on ansysV16; I have been investigated how can i put this pretesnion on beam elements and the answer was using APDL comands but i haven´t found wich of them I must use.

thanks for you answer.

Insert a Bolt Pretension, then pick a line body that is meshed with beam elements. What is stopping you from doing that?

The only requirement is that the line body must have a minimum of 2 elements along the length. If there is only 1 element, it will fail.
