The finite-sliding contact formulation requires that Abaqus/Standard continually track which part of the main surface is in contact with each secondary node. This is a very complex calculation, especially if both the contacting bodies are deformable. The structures in such simulations can be either two- or three-dimensional. Abaqus/Standard can also model the finite-sliding self-contact of a deformable body. Such a situation occurs when a structure folds over onto itself. The finite-sliding formulation for contact between a deformable body and a rigid surface is not as complex as the finite-sliding formulation for two deformable bodies. Finite-sliding simulations where the main surface is rigid can be performed for both two- and three-dimensional models. Both the contact pair algorithm and general contact can consider either small or finite sliding effects. |
