bolt pretension in submodelling
Dear Ladies and gentleman,
I want to find out the stresses on the following structure:
The modell is foxed on the left side anbd on the right side there is a fore and a moment.
I am interested in the stresses of the yellwo one. Because the modell is very big, I want to look closer inside with a submodell.
So I connected it as you can see below:
For the imported cut boundary constraints I selected all faces which are in contact with other parts or at where I cut through my modell.
I also put in the bolt pretension on my sub modell, therefore I divided the pretension force through the cross section area of the bolt in the whole modell and then multiplied it with the new cross section area in the submodell.
Then I get following results:
I am not sure if this could be correct because there is something strange in the marked area.
So I also included an extra area for the cut boundary constraints as you ca see below:
But then the solution looks quite more wrong.
I am espacially interested in the marked areas bellow:
Can anyone help me please?
