Channels by Time
The Channels by Time table lists all data points collected in arrays during Data Acquisition activities. Click
the drop-down button to select the data acquisition activity. Specify the cycle by clicking on the Numeric or
Variable button and select one or more cycle numbers or variables. Arrays included by default include:
• Cycle Index
• Array Index
• Running Time Array
• Displacement Array
• Load Array
• Strain Array
• Elastic Strain Array
• Inelastic Strain Array
• Stress Array
• Stress Array with Ramp to Mean
• Running Time Array with Ramp to Mean
Summary Data Table
The Summary Data table provides the final values of the variables defined in the Variable Editor. You can
change one or more values in this table and rerun the calculations in the same way described for the Analysis
Inputs table. After you refresh the values, the ones you modified have check marks in the Modified column.
The original test data is not lost and does not change.
Charts
The charts provide visual indicators of the data reported in the tables.
• Strain Peak Valley chart shows the strain peak and valley for each cycle of the test.
• Strain vs. Time chart shows changes in the strain during the test.
• Load Peak Valley chart shows the load peak and valley for each cycle of the test.
• Stress Peak Valley chart shows the stress peak and valley for each cycle of the test.
• Stress vs. Time chart shows changes in the stress during the test.
• First Cycle Modulus chart shows the modulus of the first cycle from the start point to the end point.
• Stress vs. Strain chart shows traces of the stress in relation to strain for the first modulus cycle, the third
cycle, the stable cycle, and the last strain cycle.
• Loading Unloading chart shows traces of the stress in relation to strain with markers to indicate the loading
and unloading start and end.
• Stress vs. Inelastic Strain chart shows traces of stress in relation to inelastic strain for the third cycle,
half-life cycle timed, and the last strain cycle.
• Inelastic Strain Min Max chart shows traces for minimum and maximum calculated values for the inelastic
strain.
• Failure Cycle chart shows the traces for the selected Y-axis variable with markers to indicate the failure
point and the half-life cycle peak valley. Drop-line markers indicate the slope of the trace.
• Modulus chart shows traces for the calculated loading and unloading modulus.
