Video is especially adapted (and highly recommended) for big strain tests. Since it is contactless, our system does not modify the testing material; and since it is a high resolution system, it can measure strains up to fracture with high precision. Our extensometer is class 1 compliant for big strains (+1200%).

Design of experiments:

  • Natural rubber, latex (big elongations) :
    • Traction: Measurements of axial strain (1200%) on latex, polyurethane (yellow, blue, red, brown...) materials at 500 mm/min.
    • Measurements of crack propagation on test specimen with a pre-crack.
    • Measurements of section reduction without pre-marking the test specimen.
    • Measurements of axial strain without pre-marking the test specimen.
