MATERIAL TESTING application example

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

The strain sensor 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.

This application example shows how an RTSS camera system can be used as a non-contact strain sensor to determine E-modules on plastics and metals.
