MTS Multipurpose Simulated - Manual (Page 61)

Description Parameter
Specify the cycle frequency of the command
signal. FCG Frequency
Specify the wave shape of the command
signal. FCG Wave Shape
The choices are True Sine or True Ramp.
Typically, you use a True Ramp wave shape
where uniform strain-rate sensitivity is
important, and a True Sine wave shape
where a continually varying strain rate is
acceptable because of the higher frequencies
of some tests.
Specify the voltage that is measured at this
load level. This parameter is used only for
FCG DCPD tests. FCG Measure Load Level

Data Storage Parameters
Description Parameter
Specify the percentage of precrack activity
that must complete before data is saved to
disk. Precrack Save Percent
Limit
Specify the cycle intervals written to disk
during the precrack activity. Store Every Nth Pre-crack
Cycle
Specify the lower load limit for linear least
squares fit compliance used to determine
when to start saving data to disk. Lower Least Squares Fit
Percentage
Specify the upper load limit for linear least
squares fit compliance used to determine
when to start saving data to disk. Upper Least Squares Fit
Percentage
5.4.2.8.0 Test Termination Parameters
Test Termination Parameters
Description Parameter
Specify Yes to end the test when the COD
limit is reached. COD Limit
