Plotting a performance index on the chart axis

Plot performance indices on a chart for a specific design situation.

In the Stage Settings dialog box:

  1. Select Performance Index Finder at the top of the axis tab.
  2. Select a Function and Loading component from the list.
    The performance index figure and description will be shown. The Equation for the Performance Index is displayed, and whether the index should be Minimized or Maximized.
  3. Select the other component definition settings, if required. They will only be active if a further choice of settings is applicable.
  4. If applicable, select Cyclic loading.

    Cyclic loading only applies to performance indices for strength limited designs, and should be selected when the component is subjected to a high level (10^7 cycles) of cyclic loading. When selected, the performance index uses the fatigue strength (at 10^7 cycles) in place of the yield strength.

    If cyclic loading is not selected, then the loading condition is taken as static. Note: the cyclic loading setting is only visible if you have the option to set it. In the situations where cyclic loading is always true, the setting will not be visible.

  5. Adjust the axis settings, if required.
