MTS Multipurpose Elite - Manual (Page 256)

Parameters
ForceArray – The array containing force data.
StrainArray – The array containing Strain data.
StartIndex – The start index of the modulus region.
EndIndex – The end index of the modulus region
Tolerance – The percentage of the peak force used to locate the transition point.
AfterPeakFlag – An optional flag to specify looking for transition point after the peak load.
Unit Class
Strain
Example
Tolerance = 98% (shown at blue oval)
The point is found where the load value is 98% of the peak load. Then a line parallel to the modulus line
is drawn from this point back to the x-axis. The Plastic strain is the difference in strain values as shown
on the graph.
Plastic Strain Value
pow(base, exponent)
A number (base) is raised to an exponential power (exponent).
Returns
Returns the value of the base raised to the power specified by the exponent.
