I would like to calculate a screw connection in RFEM using FEM. Is there a possibility in the material library to select the material according to the strength class of the screw (eg 8.8)?


The stiffness of the bolt does not depend on the strength class and is 210000 N / mm² for most steels. It is therefore possible to select an S235 as the material of the bolt to consider the stiffness of the bolt.
