40.5.2 Axisymmetric rigid surface contact element library

Product: Abaqus/Standard

References

Overview

This section provides a reference to the axisymmetric rigid surface contact elements available in Abaqus/Standard.

Element types

IRS21A Axisymmetric rigid surface contact element for use with first-order axisymmetric elements
IRS22A Axisymmetric rigid surface contact element for use with second-order axisymmetric elements

Active degrees of freedom

1, 2 at each node except the last node

1, 2, 6, the motion of the rigid body reference node, at the last node

Additional solution variables

Two additional variables at each node relating to the contact stresses.

Nodal coordinates required

r, z

Element property definition

Input File Usage:

Use the following option to define the surface with which the elements interact:

*RIGID SURFACE

Use the following option to define the rigid surface element's section properties:

*INTERFACE

Element-based loading

None.

Element output

S11	Pressure between the element and the rigid surface in the direction of the normal to the rigid surface.

S12	Shear component of the stress between the element and the rigid surface in the direction of the tangent to the rigid surface.

E11	Separation of the surfaces in the direction of the normal to the rigid surface at the closest point of the surface to the integration point on the element.

E12	Accumulated relative tangential displacement of the surfaces.

Node ordering on elements

The first two nodes in IRS21A and the first three nodes in IRS22A are on the deforming mesh. The last node is the rigid body reference node that defines the motion of the rigid body.

Numbering of integration points for output

The integration points are located at the nodes that lie on the surface of the deforming model and are numbered correspondingly.
