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

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

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

(OP)
Hi,
Should linear or non-linear FEA be used for a plastic(material) snap-fit? Thanks!

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

How do you want to solve a nonlinear problem with linear FEA? ponder

RE: 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)
