Annular snap-fit

I'm designing 2 objects that should be attached to each other and removed when it's necessary. So I though about snap-fit as a solution. There is a lot of types of snap-fit but I'm planing to use a circular one do you know what are the parameters that should be respected to make a good snap fit? is it necessary to make force,stress concentration, creep/relaxation and fatigue calculation knowing that the two designed objects are small and not heavy at all. is it possible to make snap-fit simulation using solidworks ?
