The Variable Table for Multiple Runs and Variable-Column Boundary Table for Multiple Runs tables open.
6.3.3.0 Failure Cycle Analysis Example
A Failure Cycle chart provides information about specimen failure. To obtain successful results, define Y-axis
and X-axis data arrays with corresponding cycle number values. For example, a test run samples the load
peak-valley data.
A Failure Cycle analysis requires several variables. To access the Variables Editor, right-click the analysis
run in Explorer, and select View Definition Variables.
1. Click the New Variable button, type LoadPeak, and click OK.
2. Type the following values into the table.
