Linear or Non-Linear FEA for plastic (material) snap-fit?

Up to you to decide based on material/geometry/loading. In the past I've used nonlinear FEA due to:
Large displacements of the parts voiding small displacement assumption (geometrical non-linearity)
Snap fit analyses have generally involved contact between two or more parts (boundary non-linearity).
Plastic materials were typically non-linear under the operational loading conditions (material non-linearity)

What questions are you trying to ask of the model? What experimental data do you have to feed the model? How do you plan on validating the model?
