METHOD OF DETERMINING MECHANICAL PARAMETERS OF MATERIAL MEDIUM IN FIXED EXTERNAL ACTION CONDITIONS

摘要

FIELD: physics.;SUBSTANCE: method of determining mechanical parameters of a disrupted material medium in fixed external action conditions includes determining an external action physical parameter which is definitive for the analysed medium - temperature T(°C), density ρ (kg/cm³), gravitational acceleration (g, m/s²) and material body acceleration (α, m/s²), optical radiation, radioactivity, electrical and magnetic action; setting the required mechanical parameter of the material medium taking into account the effect of physical definitive parameters of the external action; determining internal friction angle and specific cohesion s_str (kG/cm²) of the structured (natural) medium. Parameters of the internal friction angle and specific cohesion s_n of the disrupted medium are determined under fixed external action conditions using the expression ; (kG/cm²), and mechanical parameters of the material medium are determined using the determined parameters and s_n, and s_str in given external action conditions.;EFFECT: enabling determination of known mechanical parameters of a disrupted material medium through universal physical strength parameters - internal friction angle and specific cohesion, which are inherent to all material media in a structured or disrupted state.
