Modeling Bolt Connection Using Surface Releases

Ich möchte eine Bolzenverbindung, welche ausschließlich Druckspannungen aus der Lagerung aufnehmen kann, mittels Flächenfreigaben modellieren. Leider gelingt mir das nicht, da mein Modell immer instabil wird. Gibt es ein Modell als Vorlage?


Answer:

The best way is to create the bolt as a single solid and not from several partial solids (within the hole). Then, you can arrange the surface release between the contact surfaces of the solids. In the case of a bolt connection, the setting for the surface release type would have to be defined with a nonlinearity in the uz direction.

As an alternative, you can also enter releases and spring stiffnesses for the other directions.
