E N KHRUSTALEV METHOD FOR DETERMINING BOUNDARIES OF ELASTIC PHASE STRESS-STRAIN STATE OF MATERIAL MEDIUM IN THE ARRAY Russian patent published in 2016 - IPC G01N3/12

Abstract RU 2576539 C2

FIELD: physics.

SUBSTANCE: invention relates to determination of boundaries of elastic State of material medium in the array. Proposed after determination of physical parameters of the structured medium in the array-internal friction angle and specific cohesion c_{thermal control system} (kg/cm²) and specific weight of γ_tcs (kg/cm²) determination of the upper border of the elastic State of medium through the value of gravity (domestic) pressure lower bound elastic State structured medium - through the value and lower bound elastic State of the medium with a deformed structure is through the value where σ_{t. col}, σ_TR - limits of the medium flow under compression and tension c_h= c_tcs[2-(tgφ_tcs/tgφ_h)] (kg/cm²), and through the expression

value determined "tooth" fluidity of elasto-viscous-elastic material medium.

EFFECT: high accuracy of determining the boundaries of elastic state of deformable soil in the array.
