Contact problems assume small displacements by default. This lesson demonstrates that this assumption can cause convergence to a wrong solution when the actual displacements are large. Using the large displacement function causes convergence to the correct solution.
In this lesson, you learn the following:
- Applying prescribed displacement
- Defining local contact with friction
- Running the contact problem and assessing contact results
- Activating large displacement contact and rerunning the problem
- Listing the contact, friction, and reaction forces
