Principles of elementary non-wave theory of field of ultrasonic transducers used for pulse-amplitude defectometry

International Journal of Materials and Product Technology (IJMPT), Vol. 27, No. 3/4, 2006

Abstract: With the exception of the symmetry of problems, fields, structures and boundaries, the asymmetry of conditions of field spreading is also important: in medium without a sound attenuation (perfect medium) and also in medium with its sound attenuation (real medium). ENTF is based on a common method of higher mathematics under initial conditions, eliminating a wave nature of processes of excitation, spreading and reflection of sound pulses. Therefore, the theory is called elementary. The direct problem of UST, solved usually using ADD-diagrams, is generally accepted to be called defectoscopy (work in the energy of field) and the inverse problem, for the solution of which the DDA-diagram has not yet been used, is called defectometry (work in the geometry of field).
