by default:
• Category
• Display Name
• Value
• Unit
• Modified
• Original Value
• Array
• Number of Stored Points
• Calculate
• Calculation
Crack Length, Min/Max K, Load by Cycles Table
The Crack Length, Min/Max K, Load by Cycles table provides values for the cycles in the FCG Cycle Array
column. Additional default columns are:
• FCG Crack Size Array (not used for FCG DCPD analysis)
• FCG K Maximum (not used for FCG DCPD analysis)
• FCG K Minimum (not used for FCG DCPD analysis)
• FCG P Max Array (not used for FCG DCPD analysis)
• FCG P Min Array (not used for FCG DCPD analysis)
• FCG COD Voltage Active Array
• FCG Crack Voltage Reference Array
Validity Results Table
The Validity Results table includes the Display Name, Value, Modified Indicator, Original Value, and
Calculation. The Display Name includes the validity criteria. The Value and Original Value columns contain
indicators that are Yes or No values. The validity of the test results can change because of changes in
test values.
da/dN, Delta K by Cycles Table
The da/dN, Delta K by Cycles table lists all data points collected in the Fatigue Crack Growth da/dN array.
If no valid points are collected, an error may occur. If data is reduced using the Secant fit method, two
valid points are required or an error may occur. If data is reduced using the Polynomial fit method, an error
