FEMAP - how to model a bolt-preload with a "dynamic load"

Experimenter
Experimenter

I've always made two loadcases:

    1: only bolt preloads,

    2: bolt preloads + maximum acting load (on surface)

When evaluating loadcase 2, the animation is of course from all the growing loads.

 

I would like the animation to be more realistic:

A starting situation with only the bolt preloads, and then on top of that the growing acting load up to its maximum.

 

Besides this it would also be great to see this new animation with only the dynamic stresses, so without the static stresses introduced by the bolt preloads.

 

Any advice on how to achieve this more realistic animation, would be great.
