Modeling Contact with Abaqus/Standard
Objective:
Understanding the interaction between bodies is essential
for solving many engineering problems. Manufacturing
processes, gears, bearings, seals, and dynamic impact
events all involve contact. Engineers at Abaqus have
developed many techniques and guidelines for solving
challenging contact problems. This seminar teaches users
how to:
- Define general contact and contact pairs
- Define appropriate surfaces (rigid or deformable)
- Model frictional contact
- Model large sliding between deformable bodies
- Analyze dynamic impact problems
- Resolve overclosures in interference fit problems
- Avoid overconstraining the model
- Avoid rigid body motions and unstable motions
- Use pre-tension sections to simulate assembly loads
Participants are given a brief overview of the contact
formulation and contact logic used in Abaqus/Standard.
The hands-on workshops provide ample opportunity to use
the concepts developed in the lectures and to learn how to
postprocess the results of a contact analysis.
Who should attend:
This course is recommended for engineers with
experience using Abaqus/Standard.

| When seals are compressed, complex contact conditions usually develop. As
this seal is compressed between two rigid bodies, the green surface folds over and contacts the red surface on the
middle portion of the seal. As the seal continues to be compressed, the middle portion bends down to correct the lowest
portion. |
