Hello,

 

I want to see how the GAP between two 3D Solid Elements changes before and after preload and external load.

 

As the image shows , the initial gap is aproximately .1 mm and after preload, aproximately 0mm. My goal is that after an external loading this gap is NOT greater than .2 mm.

 

What would you suggest for:

             Contact Property Card (Clearance, Stiffness, Tracking, SRCHDIS, MORIENT and so on)?

 

Thank you!

    Under preload of bolt, you get gap=0.

    But under preload of bolt and external load, you can not get gap>0. Because the bolt preload was calculated to keep both parts in contact. If you get gap>0 during external load, your bolt et bolt preload were not calculated correctly.
