Description Parameter
Typically, operators will not store every cycle,
but will only store data when the crack grows
by a significant amount, such as 0.05 mm.
Specify the lower load limit for linear least
squares fit compliance used to determine FCG Lower Least Squares
Fit Percentage
when to start saving data to disk. This
parameter is not used for FCG DCPD tests.
Specify the upper load limit for linear least
squares fit compliance used to determine FCG Upper Least Squares
Fit Percentage
when to start saving data to disk. This
parameter is not used for FCG DCPD tests.
Specify the cycle intervals written to disk
during the test. Typically, this is more than
10,000. FCG N Cycle Save
Test Termination Parameters

Description Parameter
Specify Yes to end the test when the COD
limit is reached. COD Limit
Specify Yes to end the test when the load
limit is reached. Load Limit
Specify Yes to end the test when the
displacement limit is reached. Displacement Limit
Assign Precrack Values
Specify these parameters if the specimen was precracked on another load frame. When the precrack
parameters are specified here, you can then skip Precrack Specimen in the Main Menu window.
