Apparatus and procedure for measuring deformation in a traction test. (Machine-translation by Google Translate, not legally binding)

Apparatus for measuring the tensile deformation of a test piece, comprising: an articulated arm configured to be fixed to a test machine, wherein said articulated arm comprises at least two rigid sections (1, 2), and anchoring means (8); a guide (10) mounted on one end of the second section (2) of the articulated arm. On said guide (10) are mounted two frames (11, 12) in the form of "U", where each of said frames (11, 12) carries a respective optical sensor (15, 13), each of which ( 15, 13) has the ability to travel along said guide (10); where inside the "U" of said supports (11, 12) a specimen (17) is housed, including two lenses (16, 14) fixed to said specimen (17), said lenses (16, 14) being configured to mediate the deformation of said specimen (17) by measuring the displacement of said objectives (16, 14) by said optical sensors (15, 13).
