Returns
The fracture index is where this line intersects the curve (Type I) or where it intersects a peak if it comes
before this point (Type II or Type III).
Fracture Index Examples
Syntax
FractureIndex(fracture percent, slack value, Load Channel, Primary Extension channel, slope 1
index, slope 2 index)
Parameters
Fracture percent - Determines the slope at which the fracture line is drawn. This slope is a percentage of
the slope of the X-Y curve.
Slack value - The offset used for calculating slack extension. If slack compensation is not used then this
argument should be zero (0).
Load channel -The channel used for the Y-axis of the curve. This should almost always be the Load
channel.
Primary Extension channel - (PrimaryExtension) The channel used for the X-axis of the curve. This should
almost always be the PrimaryExtension channel.
Unit Class
Integer
Example
The following formula will calculate the fracture index using a 95% fracture percent and assumes that slack
compensation is turned off.
