5.9 Using the Work Tool Work or sometimes referred to as energy, is a characteristic of resil- ience or the ability of the material being tested to absorb energy. The Work algorithm calculates the area beneath the load-distance curve. The area is calculated within the scope range specified. 5.9.1 Work Algorithm The Work algorithm calculates the area beneath the load-distance curve. When the Work function is selected, you specify the scope range and the area beneath the curve for your range is highlited in blue. 5.9.1.1 Work Algorithm Scope The scope for the Minimum algorithm is based on two specific points that defined the end points of a data segment.
Or, you may implicitly specify your start and end scope points using values or other coefficients that can be used as anchors. Anchored coefficients display in yellow.
The scope range is normally not at the start of the test since the mini- mum result would be zero or at the load when the test started.
5.9.1.2 Work Algorithm Name The Work algorithm name may be changed from its default of W to Energy or N-m.
The result name may be up to 8 characters in length.
5.9.1.3 Work Algorithm Where The WHERE function is used to specify where you want the Work result to display. Display the point on any of these views: • Results View • Graph Views using a Marker • Data Views (a column within the table)
You may position the scope handles along either the y-axis or x-axis to define the data segment where you are interested in analyzing.
Work is calculated and expressed in joules.
Load-Distance Testing Mode Shows the Work within the scope segment starting at 40mm and ending at the D@lvalley result
