INSTALLATION FOR CREATION OF SINGLE-AXIS DEFORMATIONS OF SOLIDS AND FOR EXAMINATION OF THEIR PHYSICAL PROPERTIES Russian patent published in 1995 - IPC

FIELD: testing equipment. SUBSTANCE: installation uses hinged lever from which vessel for working medium is suspended with the aid of spring employed for transmission of load smoothly controlled within wide range instead of hydraulic machine. Sample is additionally centered in mandrels produced from hard alloy diminishing edge effects over its butt faces. For examination of thermal gradient effects one of mandrels centering sample is simultaneously electric heater. Registration of sample in mandrels is carried out by means of alloy providing good thermal contact with heater and cooler. EFFECT: expanded range of mechanical strains under single-axis compressions of fragile samples, expanded temperature range (4-400 K) and increased sensitivity of measuring part of installation. 3 cl, 1 dwg
