摘要：
The problem of measuring the dimensions of safe cracks by the acoustic method was considered on the basis of the concept of safe cracks. The results of investigations are presented and the obtained data on the detection and measurement of the depth of surface cracks using Rayleigh waves at artificial reflectors of the surface-notch type and at real cracks and specimens, which are subjected to cyclic loads during the “growth” of fatigue cracks, are analyzed.
