RSA-G2 Geometries
The test geometries are an important part of the sample testing procedure.
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.
Available Geometries
The following is a list of the geometries that can be used with the RSA-G2. Details for each geometry can
be found in TRIOS software Online Help.
• Linear tension (rectangular/cylindrical)
• Compression (rectangular/cylindrical)
• Three-point bending
• Clamped bending (single cantilever, dual cantilever)
• Mixed bending (single, dual)
• Shear sandwich (rectangular/cylindrical)
• Immersion (tension, compression, three-point bending)
• Contact lens
