Thank you for your answer! 

I turned off stiffness updating and this is the new graph for the bolt adjustment:

Contact settings for normal:

Thread is Bonded-MPC and frictional contacs have frictional coefficient 0,1 and a penetration value of 0,04.



In the following in changed the penetration value and compared the bolt adjustments (For comparism I changed one time also the penetration factor to 0,1):


For this test, there is just the preload (48458N) and no working load. Reason for this is that I want to measure the deformation/resilience of the bolt and compare it with the calculated value.



Thank you for your help!
