8.2.1.0 Strain Test Parameters
Strain test parameters are entries you make to control the strain test. For tests that use a sine wave command,
strain test parameters include:
• End level 1
• End level 2
• Cycle frequency
The application checks the values you enter to make sure they are within the system capabilities.
8.2.2.0 Strain Termination Parameters
Strain Termination Parameters
Description Item
Specify the number of cycles after which the
specimen is assumed to be stable and beyond cyclic
hardening or softening. Cycles for Stable
Cycle
Specify a percentage that is used to calculate
peak-valley stability. Stable Cycle
Percent
Specify a percentage that is used to calculate the
stable load range and crack initiation. Crack Initiation
Change
Specify a percentage that is used to calculate the
stable load range and specimen failure. Load Failure
Change Percent
Specify a percentage that is used to calculate if the
control peak or valley occurs outside the control
range. Peak Level
Control Change
Specify a number of cycles for the maximum length
of the test. Total Cycles
