Contact I
With this deck you can calculate contact between two plates. Differences between the keywords *CONTACT_NODES_TO_SURFACE, *CONTACT_SURFACE_TO_SURFACE and *CONTACT_ONE_WAY_SURFACE_TO_SURFACE can be studied.
Contact II
This corresponds to the previous example. Usage of *CONTACT_AUTOMATIC_SINGLE_SURFACE and *CONTACT_FORCE_TRANSDUCER_PENALTY keywords is shown.
Contact III
A box is lying on a plate. Contact between box bottom nodes and plate is specified with *CONTACT_TIED_NODES_TO_SURFACE keyword. A second plate above them is given an initial velocity in direction of the box. Contact between second plate and box upper nodes is specified with *CONTACT_AUTOMATIC_NODES_TO_SURFACE keyword.
Contact IV
This series of examples shows how to scale the penalty stiffness in contact problems. The influence of this scaling on the solution is shown by the example of a soft ring in contact with a rigid wall. In this first example the penalty factor obviously is to low.
Contact V
This series of examples shows how to scale the penalty stiffness in contact problems. The influence of this scaling on the solution is shown by the example of a soft ring in contact with a rigid wall.
Contact VI
This series of examples shows how to scale the penalty stiffness in contact problems. The influence of this scaling on the solution is shown by the example of a soft ring in contact with a rigid wall.
Twobars
This is a small example of one bar impacting a second one. Surface to surface contact is employed.
