CALCULATION MODEL OF AN ACOUSTIC CHANNEL OF THE ANGLE BEAM PROBE AT A ULTRASONIC TECHNIQUE OF MATERIAL THROUGH IS TRANSVERSAL-ISOTROPIC ELASTIC LAYER FOR THE REFLECTORS SUCH AS A DIHEDRON AND A SIDE OF THE CYLINDRICAL HOLE
(pp. 4-13)

Abstract. On the basis of model of calculation of displacement of a shear wave which is radiated the angle beam probe on environment through anisotropic (transversal – isotropic) a layer, the formulas of an acoustic сhannel for reflectors such as a direct dihedron and lateral cylindrical opening are obtained. The conducted numerical calculations for the cylindrical reflector have shown, that with increase of an anisotropy the maximum of a signal displaces in a direction to the reflector, and the signal amplitude in a maximum increases a little. Is established, that the maiden feature is connected to reduction of speed of a quasishear wave in a layer and value of a angle of a propagation direction of this wave, that displaces a beam index of a shear wave on material, and second – with increase at ascending an anisotropy of a layer of a module of product of factors of a straight line and return transformation of a longitudinal wave (in a prism of the angle beam probe) and quasishear wave (in is transversal – isotropic layer).

Keywords: angle beam probe, quasishear wave, anisotropy, transversely isotropic layer, thickness of a layer, acoustic сhannel, angle of probe, dihedron, side of the cylindrical hole, directivity characteristic, ultrasonic technique, surface of the control.
