Hi there,

is it possible to create an accurate simulation somehow with additional stress from threadlock?

As seen in the picture my bolt has a high-strenght threadlock what is realy stiff, and screwed in it stretches the tube diameter with +0,1 mm (and cause initial stress)

I made simulations without the threadlock but the results of the real life tests were really different as the simulations (with several outer thread run-out  variations, the "optimized" version was worse than the initial :), so it means i can not ignore it.

(the tube has internal pressure)

i do not have an idea, maybe if i pick up temperature to reach this initial deformation but than the surfaces of the thread won fit together.
