Bonded contact (as if objects are ideally glued together) with compatible mesh option (nodes of the objects are
shared) was used. Direct contact between the parts (no penetration condition for touching faces) was not modeled. The analyses were performed using a finite deformation formulation with the major assumption that the material behavior is linearly elastic. Therefore, the stresses could be excessively high because this analysis does not take into account plastic nature ofthe material once the yield stress has been reached. This is consistent with the purpose of the analysis to determine how much ofthe structure is exceeding the elastic limit of the material.
