For materials used for energy absorption such as elastomers, a modulus which characterizes the performance of the polymer under an oscillating load is the dynamic modulus of elasticity, E dyn = CIf 2 where C is a geometry dependent constant, I is the moment of inertia of the beam and weights used in the test, and f is frequency of vibration. Hardness (Mohs, Rockwell, Brinell, Knoop, Vickers, Durometer, Barcol)

Unformatted text preview: A simple alternative to tensile test. The test measures resistance to indentation by pressing an indenter into the material with a specific load and calculating a hardness number. The hardness number is based on a formula using indentation geometry measurements. It is a NDE (non-destructive examination). Sometimes the hardness number can be correlated to the T.S. of the material....
