  • Method and system for the non-destructive testing of a mechanical part
    Patent number: 11747307
    Abstract: A method for non-destructive testing of a mechanical part by a multi-element transducer having piezoelectric elements, where: for each element e(i) of the transducer, the emission of an ultrasonic wave at a given frequency and measurement, by each element e(j) distinct from the element e(i), of a time-varying signal kij(t) representing the back-scattered ultrasonic wave received by the element e(j); the determination of a first matrix of time-varying components based on measured signals kij(t), i, j=1, . . . , N; the determination of a second matrix of frequency components corresponding to a determined frequency based on the frequency of the ultrasonic wave by applying a Fourier transform to said first matrix; the filtering of said second matrix comprising a projection of it onto a single scattering sub-space determined by means of a numerical calculation using a ray tracing algorithm; and the verification of the integrity of the mechanical part by using said filtered second matrix.

  • METHOD AND SYSTEM FOR THE NON-DESTRUCTIVE TESTING OF A MECHANICAL PART
    Publication number: 20210239652
    Abstract: The invention relates to a method for the non-destructive testing of a mechanical part (2) by propagation of ultrasonic waves accomplished by means of a multi-element transducer (3) placed opposite the mechanical part and comprising a plurality of piezoelectric elements e(1), e(2), . . . , e(N), N>1. It comprises: for each element e(i) of the transducer, the emission of an ultrasonic wave at a given frequency and measurement, by each element e(j) distinct from the element e(i), of a time-varying signal kij(t) representing the back-scattered ultrasonic wave received by the element e(j); the determination of a first matrix of time-varying components based on the measured signals kij(t), i,j=1, . . .
