DEVICE FOR COMPRESSION TESTING OF SPECIMENS FROM SHEET AND BAR MATERIALS Russian patent published in 2024 - IPC G01N3/08 

FIELD: testing.

SUBSTANCE: invention relates to devices for compression testing of sheet and bar materials. Device comprises top plate (1) with puncheon (2) and posts (3) installed on it. In slots of posts (3) with the help of screws (4) master plates (5) are fixed. Turning of master plates (5) is performed by means of adjusting screws (15). Lower part of device consists of bed (6), in slots of which there are slides (7) with support plates (8). On the side surface of slides (7) slats (10) with slots are fixed by screws (9), in which stops (11) are fixed by means of nuts. Cover (12) is fixed on bed (6). Cover (12) fixes position of slides (7) with possibility of their movement along bed (6) slots. In master plates (5) there are slots, the angle of inclination of which is determined taking into account the mechanical properties of the material and the dimensions of the sample.

EFFECT: reduced labour intensity of tests, expanded technological capabilities of tests, increased accuracy of determination of material resistance to deformation at uniaxial stress state.
