MTS Multipurpose Elite - Manual (Page 251)

Note:
Unlike plastic strain, there is no flag to set whether the specified load point should be found after
the peak or before. This is because the Elastic Strain value would be the same in either case.
Elastic Strain Value
EnergyValue
The EnergyValue function calculates the area under the curve defined by the Y and X axis data. If using
the Force and Extension data, this function returns the amount of energy absorbed by the specimen during
the test.
Returns
The area under the curve.
Syntax
EnergyValue(y-axis, x-axis, startIndex, endIndex)
Unit Class
X-Axis unit / Y-Axis unit
Example 1
EnergyValue (_Load, SlackExt, 0 , SizeOfArray(_Load)-1)
This formula calculates the area under the entire Load versus Extension curve (energy).
Example 2
EnergyValue (_Load, SlackExt, 0, Peak)
This formula calculates the area under the Load versus Extension curve (energy) up to the peak load.
