METHOD TO MEASURE MECHANICAL PROPERTIES OF MATERIAL UNDER CONDITIONS OF CONFINED PRESSURE (VERSIONS) Russian patent published in 2014 - IPC G01N3/08 

FIELD: measurement equipment.

SUBSTANCE: invention relates to the field of research, namely, measurement of mechanical properties of solid materials, for instance, solid geological rocks under conditions of hydrostatic pressure, and may be used for the assessment of their quality, namely, their strength and modulus of elasticity during compression. Substance: a material sample surrounded by highly-plastic metal is placed in a matrix of a device providing for conditions of hydrostatic pressure at the sample. Load is applied by two puncheons, besides, the external puncheon sets hydrostatic pressure at the material sample as it impacts the highly-plastic metal, and the inner puncheon provides load directly to the material sample. According to the second version of the method realisation, the load at the material sample is applied by one puncheon, which sets hydrostatic pressure at the sample as it impacts highly plastic metal and simultaneously provides the load directly to the material sample, besides, the matrix of the device has a channel, by the cross section of which they determine hydrostatic pressure impacting the material sample.

EFFECT: possibility to measure mechanical properties of a material under conditions of confined pressure.
