The SimpleContact2D element is a two-dimensional node-to-segment contact element which defines a frictional contact interface between two separate bodies. The master nodes are the nodes which define the endpoints of a line segment on the first body, and the slave node is a node from the second body. The Lagrange multiplier node is required to enforce the contact condition. This node should not be shared with any other element in the domain. Information on the theory behind this element can be found in, e.g. Wriggers (2002).
NOTE:
- The SimpleContact2D element has been written to work exclusively with the ContactMaterial2D nDMaterial object.
- The valid recorder queries for this element are:
- force - returns the contact force acting on the slave node in vector form.
- frictionforce - returns the frictional force acting on the slave node in vector form.
- forcescalar - returns the scalar magnitudes of the normal and tangential contact forces.
