Example that Requires Nonlinear Capability with Linear Isotropic Material?

Ignorant question from Non-Engineer:  Can somebody give me an example of a simple simulation that cannot be done correctly with the Large-Displacement option in a Linear Static study even though it does not use a non-linear material?


I'm re-reading Paul Kurowski's excellent tutorial, "Engineering Analysis with Solidworks Simulation 20XX," and I have come across the following statement:  "All nonlinear problems presented in this chapter [so far, even the classic flat plate under pressure, which is stiffened under bending by tension] owe their nonlinearity to changes in geometry and contact taking place during the loading process.  They can be solved using a Static study with the Large displacement option selected.  Now we present a problem where nonlinear behavior is caused by nonlinear material.  This example requires Solidworks Simulation Premium..."


I have Solidworks Premium (linear static simulation only, including the large-displacement option).  All of my problems involve linear isotropic materials, and I want to better understand what kinds of problems I cannot solve without purchasing another license that I cannot afford.


Thanks for any guidance! -- John Willett
