MODEL OF CALCULATION OF DISPLACEMENT OF A SHEAR WAVE EXCITED BY THE ANGLE BEAM PROBE THROUGH AN ELASTIC LAYER WITH LINEARLY VARYING THICKNESS
(pp. 4-13)

Abstract. The model of calculation of displacement of a shear wave which is radiated the angle beam probe through an elastic plating with linearly varying thickness in a plane of incidence and under as contrasted to base metal speed of shear waves. Calculations of the directivity characteristics piezoelectric plate of the probe (on I. N. Ermolov) depending on an angle of a direction on a beam index have shown relation of displacement of a maximum of the directivity characteristics to a direction of change and angle of lean of boundary of a layer adjoining to base metal. The position of a maximum of the directivity characteristics also is determined by speed of shear waves in a layer and value of an angle beam probe. The registration of the detected features can be useful at a practical ultrasonic technique of metal through an elastic layer with non constant thickness it on a surface of the control.

Keywords: angle beam probe, shear wave, angle of probe, layer with linearly varying thickness, metal, directivity characteristic, ultrasonic technique, angle of lean, surface of the control, beam axis, method of projections.
