About contact pairs in Abaqus/Standard

Contact pairs in Abaqus/Standard:

  • can be used to define interactions between bodies in mechanical, coupled temperature-displacement, coupled thermal-electrical-structural, coupled pore pressure-displacement, coupled thermal-electrical, and heat transfer simulations;

  • are part of the model definition;

  • can be formed using a pair of rigid or deformable surfaces or a single deformable surface;

  • do not have to use surfaces with matching meshes;

  • cannot be formed with one two-dimensional surface and one three-dimensional surface; and

  • cannot be formed with cracked surfaces for enriched elements.

You can define contact in Abaqus/Standard in terms of two surfaces that may interact with each other as a “contact pair” or in terms of a single surface that may interact with itself in “self-contact.” Abaqus/Standard enforces contact conditions by forming equations involving groups of nearby nodes from the respective surfaces or, in the case of self-contact, from separate regions of the same surface. This section describes various aspects of defining contact pairs and refers to other sections for additional details.
