Non-contact measurement of very large strains during tensile tests on rubber

The RTSS-Videoextensometer can measure strains up to 1000%. Due to the high resolution camera a high measurement accuracy is achieved over the whole range.
The testing software calculates from the measured force and strain values material parameters like Young's modulus, elongation at break etc.
The RTSS system can be used for measurements according to ISO 37.

The Video shows the measurement of a rubber specimen with max. 500% strain.
