2.2 Graph Views There are a variety of different graph views available depending on the type of tests being performed. A graph is the most common method for analyzing results using the Graphical Analysis Tools. Using the graph, combined with these tools, you have an easy method for measuring and determining the results for your test. When tests are performed the following graph formats are available for viewing: • Stress x Strain • Stress x Time • Strain x Time Selecting the graph view is done be selecting the tab labeled with the respective graph view type.
Graphs are automatically scaled to a “best fit” size. Graph axes are labeled and increments are calculated based on the data rate and the “best fit” size. The following sections will illustrate the different graph views available. NOTE Certain coefficients may not be visible on a particular graph format.
Change the graph format by selecting the tab. • Stress x Strain ( σ x ϵ ) • Stress x Time ( σ x T) • Strain x Time ( ϵ x T)
The coefficient for modulus is displayed on a Stress x Strain graph, but not on the other forms because the modulus algorithm does not apply to Time graphs.
