Calculation of echo signals from a flat-bottom hole for normal probes
Source abstract
Abstract
On the basis of the earlier developed method for determining the echo-signal amplitude from a flat-bottom-hole flaw via the use of the Kirchhoff approximation for constructing DGS diagrams, signals are calculated at an arbitrary arrangement of identical normal circular transducers on the tested surface parallel to the surface of the hole. Expressions for the pressure of a reflected longitudinal wave on the receiving transducer are obtained in a scalar approximation and in a general case. Examples of numerical estimates of the echo-signal amplitudes are presented.
