Launch the Cumulative Damage Platform

Launch the Cumulative Damage platform by selecting Analyze > Reliability and Survival > Cumulative Damage. You must supply the Cumulative Damage platform with two data tables as input. The first data table is time-to-event data for each unit under test. The second data table defines the stress patterns used for each unit.

Figure 5.5 The Cumulative Damage Launch Window 

The launch window includes a separate tab for each step-stress data format. For more information about the various stress patterns, see Stress Pattern. For more information about the options in the Select Columns red triangle menu, see Column Filter Menu in Using JMP.

Each of the step-stress format tabs contains two panels for specifying variables for the model:

• The Time-to-Event panel is common to all of the step-stress formats. This panel is similar to the Fit Life by X platform launch window.

• The Stress Pattern panel is used to describe the type of stress. Consequently, its format depends on the selected step-stress tab.
