Analyze Data

Fatigue Crack Growth Analysis Definition

The template is preconfigured with an analysis definition that conforms to the analysis portion of the ASTM
standard. The analysis definition can be used to analyze the test run in either the Fatigue Analyzer or
Fracture Analyzer application and contains the following tables and charts.

Analysis Inputs Table

The Analysis Inputs table contains the parameters used for the analysis. In the Display Name column, the
FCG da/dN Curve Fit row indicates the Secant or Polynomial fit calculation method. You can make the
corrections indicated in the message log by adding or changing the input values. If the variable is an array,
the entry is added to the expansion table. Click the + at the left of the row to see a table of entries. Click
another row to activate the Refresh All Analysis Views button in the toolbar at the top of the window. When
you click that button, the application recalculates the analysis. You can change the calculation method by
changing the Value column entry of the FCG da/dN Curve Fit row. 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.
