FIELD: physics.SUBSTANCE: three-dimensional physical model of microinclusion systems for ultrasonic modelling, which is made from solidified elastic isotropic material, containing a set of elementary modules of microinclusions imitating cracks, wherein the elementary modules of microinclusions are superimposed plates glued on the periphery with a gas- or fluid-saturated gap of given size in between, said plates being made from material whose density and propagation speed of elastic vibrations respectively differ from density of the material of the model and propagation speed of elastic vibrations by values which do not exceed measurement error.EFFECT: design of a three-dimensional physical model of crack systems with possibility of varying geometric parameters of the cracks and arbitrary orientation thereof in space, much closer to real rheological objects, while providing different fluid-saturation conditions.3 cl, 5 dwg |
