Thread simulation with additional stress from threadlock?

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.
