A surface contact type indicates which forces are transferred between the surfaces defined as a surface contact.
Usage in Program
In the program, you can select several contact types. Basically, there are two different superordinate contact types. First, a "Contact Perpendicular to Surfaces," and second, a "Contact Parallel to Surfaces" can be defined.
For the "Contact Perpendicular to Surfaces," the following criteria are available in the program:
- Full force transmission: Both compression and tension forces are transferred.
- Failure under tension: The contact is released when the surfaces move away from each other.
- Failure under compression: Only tensile forces are transferred.
For the "Contact Parallel to Surfaces," the following criteria are available:
- Failure if contact perpendicular to surfaces failed
- Full force transmission
- Rigid friction
- Elastic friction
- Elastic surface behavior
These options generally control how the shear forces are transferred between the surfaces.
