QUICK-DETACHABLE SYSTEM FOR INSTALLATION OF SAMPLES FOR TESTING MATERIALS FOR BIAXIAL TENSION (VERSIONS) Russian patent published in 2024 - IPC G01N1/36 G01N3/04 G01N3/08 

FIELD: testing.

SUBSTANCE: invention relates to testing of mechanical properties of materials for example, biomaterials, for biaxial (flat) stretching, in particular to devices for installing samples in a material testing stand or for installation in a testing machine. According to the first version, the quick-detachable sample installation system includes a mounting platform with a central hole, on which rake-type retainers and platforms with grooves are installed, for placing rakes of retainers in them, a template-navigator for placing a sample on it and corresponding to or smaller than the central hole of the mounting platform, wherein rake ends are arranged along edges of template-navigator and clamp plate to lock rake in platform grooves. According to the second version, the quick-detachable system for installation of samples includes a mounting platform with a central hole and guides made in the form of rails, retainers with pulleys. Retainers are installed on the mounting platform guides and are made with possibility of movement along the rails. Installation includes a template-navigator for placing a sample on it and a corresponding or smaller hole of the mounting platform.

EFFECT: providing rapid installation of retainers with a sample in a test bench (testing machine) for testing samples for biaxial tension, providing reliable installation of samples and retention thereof on retainers, ensuring uniform distribution of load on the sample, providing fixation and analysis of sample without uncontrolled slippage, providing installation of the sample without mechanical action on the region of interest (central region of the sample), as well as providing the possibility of analysing small-size samples and their soft tissues.
