Contact components are required to define the options in the Contact Properties section for inter-leaf contacts. METAL_METAL is the default contact. You can add any number of contacts based on the requirement.
The contact force is modeled as an Impact function:
| Note | For more information about impact, see the MotionSolve documentation on the IMPACT function. |
The following section explains the options used in the Contact Properties.
Clearness: Minimum distance above which no contact force will be applied. It is used to define spacer thickness.
Stiffness: Defines the stiffness of the contact force.
Exponent: Defines the exponent of the force deformation characteristic.
Max. Damping: Defines the maximum damping coefficient.
Max. Penetration Depth: Penetration at which the full damping coefficient is applied.
In the Contact Properties block of Leaf Property file, the attribute, type, and valid value that has to be entered in TiemOrbit file format is detailed in the following table. This table also provides the information about whether an attribute is required.
An example of how a Contact Properties block is represented in a TiemOrbit file format is shown below:
Block Name = ‘CONTACT_PROPERTIES’ (Required) |

Sub-block Name = ‘METAL_METAL’ (Default) |
