RTSS: Tensile test for the determination of Young's Modulus

The RTSS-Videoextensometer measures the longitudinal strain during tensile test and transfers the result to the tensile test machine.
The test software calculates from the time course of the measured force and strain and from the specimen dimensions material parameter like Young's modulus, elongation at break, etc.

The image shows the measures stress-strain curve with the calculated Young's modulus.
