View Contact Response

Review mechanics of connections with separating or closing contact conditions.

This feature does not support bonding or sliding contact conditions.
Five response types are available:
  • Load condition: Normal traction (contact pressure)
  • Load condition: Tangential traction
  • Displacement condition: Contact opening (deformational gap)
  • Displacement condition: Contact slippage
  • Combined status: Contact status
  1. In the Project Tree, open the Analysis workbench.
  2. In the Analysis Workbench, select Contact response.
  3. In the Project Tree, select the connection(s) to view.
  4. Select a Response type from the drop-down menu.
  5. All responses, apart from the contact status, offer quantitative measurements. The Contact status option, on the other hand, indicates whether each point in the selected connection(s) is open or closed.
    • For separating contacts with a zero initial gap, points with a zero normal gap are displayed as close-stick. Points with zero normal gap but exhibiting slippage are shown as close-slip. All other points with a gap greater than zero are displayed as open. For separating contacts with a non-zero initial gap, it is assumed that there is zero clearance between the connected parts irrespective of physical distance between the parts. The contact status of points with an initial normal gap is shown as close-stick, but if slippage is detected, the status will be marked as close-slip. Any points where the gap exceeds the initial value will be displayed as open.
    • For separating closing contacts with zero or non-zero initial gap, points with a zero normal gap are displayed as close-stick. Points with zero normal gap but exhibiting slippage are shown as close-slip. All other points with a gap greater than zero are displayed as open.
    • When Response type is set to Contact status, you can define a numerical value for what constitutes an open or slipping contact.
    OptionDescription
    Open Tolerance This setting lets you specify a minimum normal gap distance. Any point with a gap greater than this value will be considered "open," even if the default behavior would categorize it as "close-stick" or "close-slip" due to zero initial gap. This is useful for analyzing situations where a small separation is acceptable or expected.
    Slip Tolerance This allows you to set a threshold for the amount of tangential movement. If the relative tangential displacement between two parts exceeds this value, the contact will be designated as "close-slip," indicating that slippage has occurred.
  6. Use the slider to select Display point size.
    The modeling window will update to display the chosen results.
  7. Click Close.
