Page 42: Define test parameters
Description
Parameter
The value you specify here represents the slope
value of the material’s stress-strain curve in the
elastic deformation region.
Elastic Modulus (E)
Elastic Modulus is a specimen variable that other
variables may use in a calculation.
Specify the stress value at which permanent
deformation occurs.
Yield Strength
Yield Strength is a specimen variable that other
variables may use in a calculation.
Specify the temperature at which Elastic Modulus
and Yield Strength are valid.

6.2.0 Define Test Parameters
6.2.1.0 Temperature Parameters
Temperature parameters for the low-cycle fatigue strain test include:
•
High Temperature Difference
•
Low Temperature Difference
•
Soak Time
•
Start Temperature
•
Start Temperature Limit
•
Temperature Ramp
•
Time to Start Temperature
•
Zone 1 Temperature
•
Zone 2 Temperature
•
Zone 3 Temperature
The application checks the values you enter to make sure they are within the system capabilities.
6.2.2.0 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
