RTSS videoextensometer for the determination of Young's Modulus at Tensile tests

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

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