Select Stress Columns

The Select Stress Columns window is used to select which of the stress columns in your data sheet will be used in the analysis. When applicable, this window also includes drop-down lists that allow you to categorize the selected stresses. To access the window, click Select Stress Columns directly underneath the Model area of the control panel.

All of the stress columns in your data sheet are listed in the Available Stress Columns area. To use a column in the analysis, select the corresponding check box. Note that the text directly above the Available Stress Columns area provides information on how many stresses are required and how many can be used with the selected model.

Tip: You can also choose which stress columns to include in the analysis by selecting the check boxes in the column headers of the data sheet.

If you chose a temperature-nonthermal (TNT) or generalized Eyring (GER) model on the control panel, you will be required to categorize each stress as thermal or nonthermal. To use either of these models, you must select exactly two stress columns: one for a thermal stress and one for a nonthermal stress.
