# Abaqus Standard Contact Elements

## Definition

Abaqus Standard contact elements are specialized Abaqus/Standard element families for contact cases that are not best handled by surface-based general contact or contact pairs.

## How They Work

The contact element library includes gap contact elements, tube-to-tube contact elements, slide line contact elements, and rigid surface contact elements. They require element creation, section or property assignment, and contact property definitions, similar in spirit to surface-based contact but expressed through element topology.

Gap elements model contact along specified directions between nodes or between a node and a surface. Tube-to-tube elements model contact between pipes or tubes. Slide line elements support certain axisymmetric or line-based finite-sliding contact workflows. Rigid surface contact elements support specialized rigid-deformable interactions.

## Why It Matters

Surface-based contact is usually preferred, but contact elements remain useful for specialized Abaqus/Standard models such as pipe-in-pipe contact, one-dimensional thermal contact, substructure-related contact, or asymmetric-axisymmetric workflows.
