Studying internal structure of quartz by broadband ultrasonic tomography under cyclic compression

Popis výsledku v původním jazyce

The article considers the possibility of studying and identifying defects in the internal structure of synthetic quartz crystals using the parameters of acoustic emission and laser-ultrasound tomography. In the course of cyclic compressive loading, the nature of the propagation of discontinuities in a sample was investigated. It is revealed that the properties of the material, the inhomogeneity of which is associated with the presence of microdefects and anisotropy, change in the initial stages of mechanical load. With repeated application of the load on the sample, previously formed defects cause significant changes in its internal structure. With the help of numerical modeling, the obtained results were verified.
