Title: DEVICE FOR CARRYING OUT A BIAXIAL TENSILE TEST ON A MATERIAL
Abstract:
Mechanical or electromechanical device (DBT) configured to carry out a deformation test on a material, comprising an input piston and/or bar (1), a cell (CEL), which comprises a chamber (2) and a holding die element (4) for holding a blank (3) that is to be deformed. The cell (CEL) of the device (DBT) is characterized by a deliberately large mass and is secured to at least one bearing element (5) designed to press on at least one damper (6) configured to absorb some of the energy received via the input piston and/or bar (1), the device (DBT) comprising no mechanical element of the "extending bar" type.
