Resumo
The results of experimental studies of the realized sensitivity and capabilities of the shadow method in problems of detection and assessment of defect sizes by surface waves are presented. It is shown that the time shadow method has a higher sensitivity to crack-like surface defects than the amplitude shadow method, and when used together with the amplitude method, it allows estimating the size of cracks whose depth does not exceed a quarter of the wavelength. A calculation method is proposed and analytical expressions are given for determining the time position of the maximum of the digitized pulse, recommendations are given for choosing the sampling frequency. The possibility of achieving an error in measuring the propagation time not exceeding 0.2 periods of the wave frequency is shown
