Does the nonlinearity that can be activated for a surface support in the z‑direction refer to the entire supported surface, or only to the areas that correspond to the nonlinearity?

Question

Accepted Answer

The nonlinearity of surface supports—that is, "Failure if positive/negative contact stress in z"; see Image 01—only refers to the relevant area.In the remaining area, the surface support acts accordingly; see Image 02.

Effective Area of Nonlinearity for Surface Supports in z-Deirection

Does the nonlinearity that can be activated for a surface support in the z‑direction refer to the entire supported surface, or only to the areas that correspond to the nonlinearity?
