INDENTATION DEVICE, AUTOMATED MEASUREMENT SYSTEM AND METHOD FOR MATERIALS MECHANICAL PROPERTIES DETERMINATION BY INDENTATION METHOD Russian patent published in 2017 - IPC G01N3/42 

FIELD: measurement equipment.

SUBSTANCE: automated measurement system includes indentation device (1), a loading mechanism (2), a table (3) for the sample, an analog-digital converter (4) and a computer (5). The main point of indentation device (1) is the following: inside housing (6), holder (15) of movement sensor (19) is mounted which is permanently connected to housing (6), where movable rod (20) is placed being movable and extending to movement sensor (19), set in holder (15) in indenter axis (13). Movable push segment (10) in the upper part of housing (6) is provided with legs coming around holder (15) and grippable central push plate (23) disposed in housing (6) being movable and carrying at least one first dynamometer (25) with deformable projections (26). These projections (26) through gap (27) are in contact with lower push plate (28) disposed in housing (6) being movable and connected with holder (12) of indentor (13), and between lower push plate (28) and end face (7), there is a first elastic element (30), a central push panel (23) and the lower push panel (28) provided with openings for the passage of movement rod (20) in holder (15). Indentation device (1) is made in two embodiements having advantages for use with any loading mechanism (2) and for use without a loading mechanism (2) manually.

EFFECT: ability to accurately measure the indenter movement without deformation influence of the device elements, with sufficient accuracy over a wide range of loads.
