Convert Stress Values

The Convert Stress Values window is used to convert all the values entered in one of the stress columns of an ALTA standard folio data sheet. You can have the stress values multiplied or divided by a specified value, or you can convert temperature values that were entered in Celsius or Fahrenheit to one of the absolute scales supported by the software (i.e., Kelvin or Rankine).

Follow the steps outlined below:

Select the stress column that contains the values you want to convert by clicking the header of that column or selecting any cell in that column.

Note: The software will always convert all of the values in a column. For example, if you select one cell and convert the contained value, all the other values in that column will be converted as well.

Choose ALTA > Options > Convert Stress Values to open the window.

In the Convert Each Value area, select the conversion option you wish to use.
- If you select the Multiply By or Divide By option, you will enable an input field. In this field, enter the value that you wish to have each stress value multiplied or divided by.
Select the Put current values in Subset ID check box if you want the software to move the original, unconverted values into the first subset ID column in the data sheet for future reference. If there is already information in the first subset ID column, the software will overwrite that information.

Tip: If you only have one subset ID column, and you want to move its information to a column that will not be overwritten when you select the Put current values in Subset ID check box, first use the Add or Remove Columns window to add a second subset ID column. Then paste the information from the first subset ID column to the new column. The software will only overwrite values in the first ID column.

Click OK to convert all the values in the selected stress column.
