Description Parameter
Specify the rate at which the system reloads
the specimen to the load value at the JIC Reload Rate
beginning of the first unload segment in each
step increment. If the ramp rate is invalid for
the specimen being tested, the application
corrects the value of the ramp rate when you
click Run to start the test.
Specify the method for determining the
amount of force to apply in both the unload
and reload segments: JIC Unload Method
• Absolute—Specify that the amount force
to apply is in absolute terms.
• Percentage—Specify that the amount of
force to apply is a percentage of the
increment peak load.
• Minimum of absolute and
percentage—Specify that the amount
force to apply is the smaller resulting
value of the two methods above.
Specify the rate at which the system unloads
the specimen in the unload segments in each JIC Unload Rate
step increment. If the ramp rate is invalid for
the specimen being tested, the application
corrects the value of the ramp rate when you
click Run to start the test.
