ARES-G2 Geometries
The test geometries are an important part of the sample testing procedure. This section provides you with
some background information that can be used when deciding which geometry to use.
Although the physical properties of the sample generally dictate appropriate test geometry, it is sometimes
possible to test a given sample using more than one geometry. Ideally, the test results should be identical in
the different geometries. However, there exist experimental limitations that may make testing in one geom-
etry preferable to testing in another. Additionally, factors such as anisotropy and differences in strain
dependence may yield inconsistent results for different geometries.
NOTE: For more details on geometries and their usage, please refer to TRIOS software online Help.
