|modeling snap-fit in FE with discrete springs or superelements ?|
Posted by: guiguit ® |
Author Profile Mail author Edit
I d like to idealise a snap-fit for subsequent modal analysis. What is the best method, either use superelements or define stiffness (using a contact FE code) and then model the snap-fit as a set of translational and rotational springs?
What are the advantages & limitations of each approach for this special task?
thanks for your answers.
