Prestressed modal analysis.
Prestressed modal analysis.
(OP)
Dear All,
I am trying to perform a prestresssed modal analysis on a beam using Ansys, but the results are the same as the modal analysis of the beam without the static force.
Idid static analysis with prestress ON ,EXIT solution , reopen solution, then modal analysis with prestress ON.
Please could anyone help me or show me the right way to do prestressed modal analysis .
Regards,
Abdelhamid5

RE: Prestressed modal analysis.
Try to model a tensioned cable: in this case the modal behavior is highly influenced by the axial force.
