The following table lists the precrack parameters and their required values.
Precrack Parameters
Description
Parameter
Specify the desired crack size to achieve in
the precrack activity. When the specified
crack size is achieved, the activity stops.
Precrack Final Crack
Limit
Specify the cycle frequency of the command
signal for the precrack activity.
Precrack Frequency
Specify the ratio of the minimum to maximum
load applied to the specimen. The minimum
Precrack Load Ratio
load is determined by this value and the
maximum load is specified by you.
Specify the percentage of the measured load
range used as the lower limit for linear least
