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.
